* The {@code java.specification.maintenance.version} property is
* defined if the specification implemented by this runtime at the
* time of its construction had undergone a <a
* href="https://jcp.org/en/procedures/jcp2#3.6.4">maintenance
* release</a>. When defined, its value identifies that
* maintenance release. To indicate the first maintenance release
* this property will have the value {@code "1"}, to indicate the
* second maintenance release this property will have the value
* {@code "2"}, and so on.
* <p>
* Multiple paths in a system property value are separated by the path
* separator character of the platform.
