<dd>
An override for specifying the (absolute) path of where the
build output is to go.
The default output directory will be build/<i>platform</i>.
<strong>i586 only:</strong>
The location of the
<a href="#msvcr90"><tt>MSVCR90.DLL</tt></a>.
</dd>
<dt><a name="ALT_SLASH_JAVA"><tt>ALT_SLASH_JAVA</tt></a></dt>
<dd>
The default root location for many of the ALT path locations
of the following ALT variables.
The default value is
<tt>"/java"</tt> on Solaris and Linux,
<tt>"J:"</tt> on Windows.
</dd>
<dt><a name="ALT_UNIXCCS_PATH"><tt>ALT_UNIXCCS_PATH</tt></a></dt>

<strong>Solaris only:</strong>
An override for specifying where the Unix CCS
command set are located.
The default location is <tt>/usr/ccs/bin</tt>
</dd>
<dt><a name="ALT_UNIXCOMMAND_PATH"><tt>ALT_UNIXCOMMAND_PATH</tt></a> </dt>
<dd>
An override for specifying where the
Unix command set are located.
The default location varies depending on the platform,
<tt>"%SYSTEMDRIVE%/MKSNT"</tt> or
<tt>$(ROOTDIR)</tt> on Windows with MKS, otherwise it's
<tt>"/bin"</tt> or <tt>/usr/bin</tt>.
</dd>
<dt><a name="ALT_USRBIN_PATH"><tt>ALT_USRBIN_PATH</tt></a></dt>
<dd>
An override for specifying where the
Unix <tt>/usr/bin</tt> commands are located. You usually do not need
to set this variable: the default location is <tt>/usr/bin</tt>)
</dd>
<dt><a name="ANT_HOME"><tt>ANT_HOME</tt></a></dt>
<dd>
The location of the Ant installation.
See <a href="#ant">Ant</a> for more information.
You should always set <tt>ANT_HOME</tt> explicitly.
</dd>
<dt><a name="arch_data_model"><tt>ARCH_DATA_MODEL</tt></a></dt>
<dd>The <tt>ARCH_DATA_MODEL</tt> variable
is used to specify whether the build is to generate 32-bit or 64-bit
binaries.
The Solaris build supports either 32-bit or 64-bit builds, but
Windows and Linux will support only one, depending on the specific
OS being used.
Normally, setting this variable is only necessary on Solaris.
Set <tt>ARCH_DATA_MODEL</tt> to <tt>32</tt> for generating 32-bit binaries,
or to <tt>64</tt> for generating 64-bit binaries.
</dd>
<dt><tt>BUILD_NUMBER</tt> </dt>
<dd>
The build number for the build (<i>e.g.</i> "b27").
The default value is "b00".
</dd>
<dt><tt>MILESTONE</tt> </dt>
<dd>
The milestone name for the build (<i>e.g.</i>"beta").
The default value is "internal".
</dd>
<dt><a name="path"><tt>PATH</tt></a> </dt>
<dd>Typically you want to set the <tt>PATH</tt> to include:
<ul>
<li>The location of the GNU make binary</li>
<li>The location of the Bootstrap JDK <tt>java</tt>
(see <a href="#bootjdk">Bootstrap JDK</a>)</li>
<li>The location of the C/C++ compilers
(see <a href="#compilers"><tt>compilers</tt></a>)</li>
<li>The location or locations for the Unix command utilities
(e.g. <tt>/usr/bin</tt>)</li>

This is caused by a missing libstdc++.a library.
This is installed as part of a specific package
(e.g. libstdc++.so.devel.386).
By default some 64bit Linux versions (e.g. Fedora)
only install the 64bit version of the libstdc++ package.
By default some 64-bit Linux versions (e.g. Fedora)
only install the 64-bit version of the libstdc++ package.
Various parts of the JDK build require a static
link of the C++ runtime libraries to allow for maximum
portability of the built images.

// - host_class: supplies context for linkage, access control, protection domain, and class loader
// - data: bytes of a class file, a raw memory address (length gives the number of bytes)
// - cp_patches: where non-null entries exist, they replace corresponding CP entries in data
// When you load an anonymous class U, it works as if you changed its name just before loading,
// to a name that you will never use again. Since the name is lost, no other class can directly
// link to any member of U. Just after U is loaded, the only way to use it is reflectively,
// through java.lang.Class methods like Class.newInstance.
// Access checks for linkage sites within U continue to follow the same rules as for named classes.
// The package of an anonymous class is given by the package qualifier on the name under which it was loaded.
// An anonymous class also has special privileges to access any member of its host class.
// This is the main reason why this loading operation is unsafe. The purpose of this is to
// allow language implementations to simulate "open classes"; a host class in effect gets
// new code when an anonymous class is loaded alongside it. A less convenient but more
// standard way to do this is with reflection, which can also be set to ignore access
// restrictions.
// Access into an anonymous class is possible only through reflection. Therefore, there
// are no special access rules for calling into an anonymous class. The relaxed access
// rule for the host class is applied in the opposite direction: A host class reflectively
// access one of its anonymous classes.
// If you load the same bytecodes twice, you get two different classes. You can reload
// the same bytecodes with or without varying CP patches.
// By using the CP patching array, you can have a new anonymous class U2 refer to an older one U1.
// The bytecodes for U2 should refer to U1 by a symbolic name (doesn't matter what the name is).
// The CONSTANT_Class entry for that name can be patched to refer directly to U1.
// This allows, for example, U2 to use U1 as a superclass or super-interface, or as
// an outer class (so that U2 is an anonymous inner class of anonymous U1).
// It is not possible for a named class, or an older anonymous class, to refer by
// name (via its CP) to a newer anonymous class.
// CP patching may also be used to modify (i.e., hack) the names of methods, classes,
// or type descriptors used in the loaded anonymous class.
// Finally, CP patching may be used to introduce "live" objects into the constant pool,
// instead of "dead" strings. A compiled statement like println((Object)"hello") can
// be changed to println(greeting), where greeting is an arbitrary object created before
// the anonymous class is loaded. This is useful in dynamic languages, in which
// various kinds of metaobjects must be introduced as constants into bytecode.
// Note the cast (Object), which tells the verifier to expect an arbitrary object,
// not just a literal string. For such ldc instructions, the verifier uses the
// type Object instead of String, if the loaded constant is not in fact a String.

* <p>Return an {@code MBeanInfo} object that is the same as this one
* except that its descriptions are localized in the given locale.
* This means the text returned by {@link MBeanInfo#getDescription}
* (the description of the MBean itself), and the text returned by the
* {@link MBeanFeatureInfo#getDescription getDescription()} method
* for every {@linkplain MBeanAttributeInfo attribute}, {@linkplain
* MBeanOperationInfo operation}, {@linkplain MBeanConstructorInfo
* constructor}, and {@linkplain MBeanNotificationInfo notification}
* contained in the {@code MBeanInfo}.</p>
*
* <p>Here is how the description {@code this.getDescription()} is
* localized.</p>
*
* <p>First, if the {@linkplain #getDescriptor() descriptor}
* of this {@code MBeanInfo} contains a field <code><a
* href="Descriptor.html#locale">"locale"</a></code>, and the value of
* the field is the same as {@code locale.toString()}, then this {@code
* MBeanInfo} is returned. Otherwise, localization proceeds as follows,
* and the {@code "locale"} field in the returned {@code MBeanInfo} will
* be {@code locale.toString()}.
*
* <p>A <em>{@code className}</em> is determined. If this
* {@code MBeanInfo} contains a descriptor with the field
* <a href="Descriptor.html#interfaceClassName">{@code
* "interfaceClassName"}</a>, then the value of that field is the
* {@code className}. Otherwise, it is {@link #getClassName()}.
* Everything before the last period (.) in the {@code className} is
* the <em>{@code package}</em>, and everything after is the <em>{@code
* simpleClassName}</em>. (If there is no period, then the {@code package}
* is empty and the {@code simpleClassName} is the same as the {@code
* className}.)</p>
*
* <p>A <em>{@code resourceKey}</em> is determined. If this {@code
* MBeanInfo} contains a {@linkplain MBeanInfo#getDescriptor() descriptor}
* with a field {@link JMX#DESCRIPTION_RESOURCE_KEY_FIELD
* "descriptionResourceKey"}, the value of the field is
* the {@code resourceKey}. Otherwise, the {@code resourceKey} is {@code
* simpleClassName + ".mbean"}.</p>
*
* <p>A <em>{@code resourceBundleBaseName}</em> is determined. If
* this {@code MBeanInfo} contains a descriptor with a field {@link
* JMX#DESCRIPTION_RESOURCE_BUNDLE_BASE_NAME_FIELD
* "descriptionResourceBundleBaseName"}, the value of the field
* is the {@code resourceBundleBaseName}. Otherwise, the {@code
* resourceBundleBaseName} is {@code package + ".MBeanDescriptions"}.
*
* <p>Then, a {@link java.util.ResourceBundle ResourceBundle} is
* determined, using<br> {@link java.util.ResourceBundle#getBundle(String,
* Locale, ClassLoader) ResourceBundle.getBundle(resourceBundleBaseName,
* locale, loader)}. If this succeeds, and if {@link
* java.util.ResourceBundle#getString(String) getString(resourceKey)}
* returns a string, then that string is the localized description.
* Otherwise, the original description is unchanged.</p>
*
* <p>A localized description for an {@code MBeanAttributeInfo} is
* obtained similarly. The default {@code resourceBundleBaseName}
* is the same as above. The default description and the
* descriptor fields {@code "descriptionResourceKey"} and {@code
* "descriptionResourceBundleBaseName"} come from the {@code
* MBeanAttributeInfo} rather than the {@code MBeanInfo}. If the
* attribute's {@linkplain MBeanFeatureInfo#getName() name} is {@code
* Foo} then its default {@code resourceKey} is {@code simpleClassName +
* ".attribute.Foo"}.</p>
*
* <p>Similar rules apply for operations, constructors, and notifications.
* If the name of the operation, constructor, or notification is {@code
* Foo} then the default {@code resourceKey} is respectively {@code
* simpleClassName + ".operation.Foo"}, {@code simpleClassName +
* ".constructor.Foo"}, or {@code simpleClassName + ".notification.Foo"}.
* If two operations or constructors have the same name (overloading) then
* they have the same default {@code resourceKey}; if different localized
* descriptions are needed then a non-default key must be supplied using
* {@code "descriptionResourceKey"}.</p>
*
* <p>Similar rules also apply for descriptions of parameters ({@link
* MBeanParameterInfo}). The default {@code resourceKey} for a parameter
* whose {@linkplain MBeanFeatureInfo#getName() name} is {@code
* Bar} in an operation or constructor called {@code Foo} is {@code
* simpleClassName + ".operation.Foo.Bar"} or {@code simpleClassName +
* ".constructor.Foo.Bar"} respectively.</p>
*
* <h4>Example</h4>
*
* <p>Suppose you have an MBean defined by these two Java source files:</p>
*
* <pre>
* // ConfigurationMBean.java
* package com.example;
* public interface ConfigurationMBean {
* public String getName();
* public void save(String fileName);
* }
*
* // Configuration.java
* package com.example;
* public class Configuration implements ConfigurationMBean {
* public Configuration(String defaultName) {
* ...
* }
* ...
* }
* </pre>
*
* <p>Then you could define the default descriptions for the MBean, by
* including a resource bundle called {@code com/example/MBeanDescriptions}
* with the compiled classes. Most often this is done by creating a file
* {@code MBeanDescriptions.properties} in the same directory as {@code
* ConfigurationMBean.java}. Make sure that this file is copied into the
* same place as the compiled classes; in typical build environments that
* will be true by default.</p>
*
* <p>The file {@code com/example/MBeanDescriptions.properties} might
* look like this:</p>
*
* <pre>
* # Description of the MBean
* ConfigurationMBean.mbean = Configuration manager
*
* # Description of the Name attribute
* ConfigurationMBean.attribute.Name = The name of the configuration
*
* # Description of the save operation
* ConfigurationMBean.operation.save = Save the configuration to a file
*
* # Description of the parameter to the save operation.
* # Parameter names from the original Java source are not available,
* # so the default names are p1, p2, etc. If the names were available,
* # this would be ConfigurationMBean.operation.save.fileName
* ConfigurationMBean.operation.save.p1 = The name of the file
*
* # Description of the constructor. The default name of a constructor is
* # its fully-qualified class name.
* ConfigurationMBean.constructor.com.example.Configuration = <!--
* -->Constructor with name of default file
* # Description of the constructor parameter.
* ConfigurationMBean.constructor.com.example.Configuration.p1 = <!--
* -->Name of the default file
* </pre>
*
* <p>Starting with this file, you could create descriptions for the French
* locale by creating {@code com/example/MBeanDescriptions_fr.properties}.
* The keys in this file are the same as before but the text has been
* translated:
*
* <pre>
* ConfigurationMBean.mbean = Gestionnaire de configuration
*
* ConfigurationMBean.attribute.Name = Le nom de la configuration
*
* ConfigurationMBean.operation.save = Sauvegarder la configuration <!--
* -->dans un fichier
*
* ConfigurationMBean.operation.save.p1 = Le nom du fichier
*
* ConfigurationMBean.constructor.com.example.Configuration = <!--
* -->Constructeur avec nom du fichier par d&eacute;faut
* ConfigurationMBean.constructor.com.example.Configuration.p1 = <!--
* -->Nom du fichier par d&eacute;faut
* </pre>
*
* <p>The descriptions in {@code MBeanDescriptions.properties} and
* {@code MBeanDescriptions_fr.properties} will only be consulted if
* {@code localizeDescriptions} is called, perhaps because the
* MBean Server has been wrapped by {@link
* ClientContext#newLocalizeMBeanInfoForwarder} or because the
* connector server has been created with the {@link
* javax.management.remote.JMXConnectorServer#LOCALIZE_MBEAN_INFO_FORWARDER
* LOCALIZE_MBEAN_INFO_FORWARDER} option. If you want descriptions
* even when there is no localization step, then you should consider
* using {@link Description &#64;Description} annotations. Annotations
* provide descriptions by default but are overridden if {@code
* localizeDescriptions} is called.</p>
*
* @param locale the target locale for descriptions. Cannot be null.
*
* @param loader the {@code ClassLoader} to use for looking up resource
* bundles.
*
* @return an {@code MBeanInfo} with descriptions appropriately localized.
*
* @throws NullPointerException if {@code locale} is null.
