/* Within this implementation of the com.sun.star.java.JavaVirtualMachine

* com.sun.star.java.XJavaVM.getJavaVM relies on the following:
* 1 The string "$URE_INTERNAL_JAVA_DIR/" is expanded via the
* com.sun.star.util.theMacroExpander singleton into an internal (see the
* com.sun.star.uri.ExternalUriReferenceTranslator service), hierarchical URI
* reference relative to which the URE JAR files can be addressed.
* 2 The string "$URE_INTERNAL_JAVA_CLASSPATH" is either not expandable via the
* com.sun.star.util.theMacroExpander singleton
* (com.sun.star.lang.IllegalArgumentException), or is expanded via the
* com.sun.star.util.theMacroExpander singleton into a list of zero or more
* internal (see the com.sun.star.uri.ExternalUriReferenceTranslator service)
* URIs, where any space characters (U+0020) are ignored (and, in particular,
* separate adjacent URIs).
* If either of these requirements is not met, getJavaVM raises a
* com.sun.star.uno.RuntimeException.
