/* Within this implementation of the com.sun.star.java.JavaVirtualMachine
 * service and com.sun.star.java.theJavaVirtualMachine singleton, the method
 * 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.
