/**
* The {@code ClassFileVisitor} reads a class file using the
* {@code com.sun.tools.classfile} library. It iterates over the methods
* in a class, and checks MethodParameters attributes against JLS
* requirements, as well as assumptions about the javac implementations.
* <p>
* It enforces the following rules:
* <ul>
* <li>All non-synthetic methods with arguments must have the
* MethodParameters attribute. </li>
* <li>At most one MethodParameters attribute per method.</li>
* <li>An empty MethodParameters attribute is not allowed (i.e. no
* attribute for methods taking no parameters).</li>
* <li>The number of recorded parameter names much equal the number
* of parameters, including any implicit or synthetic parameters generated
* by the compiler.</li>
* <li>Although the spec allow recording parameters with no name, the javac
* implementation is assumed to record a name for all parameters. That is,
* the Methodparameters attribute must record a non-zero, valid constant
* pool index for each parameter.</li>
* <li>Check presence, expected names (e.g. this$N, $enum$name, ...) and flags
* (e.g. ACC_SYNTHETIC, ACC_MANDATED) for compiler generated parameters.</li>
* <li>Names of explicit parameters must reflect the names in the Java source.
* This is checked by assuming a design pattern where any name is permitted
* for the first explicit parameter. For subsequent parameters the following
* rule is checked: <i>param[n] == ++param[n-1].charAt(0) + param[n-1]</i>
* </ul>
