-/**
- * Anonymous class loader.  Will load any valid classfile, producing
- * a {@link Class} metaobject, without installing that class in the
- * system dictionary.  Therefore, {@link Class#forName(String)} will never
- * produce a reference to an anonymous class.
- * <p>
- * The access permissions of the anonymous class are borrowed from
- * a <em>host class</em>.  The new class behaves as if it were an
- * inner class of the host class.  It can access the host's private
- * members, if the creator of the class loader has permission to
- * do so (or to create accessible reflective objects).
- * <p>
- * When the anonymous class is loaded, elements of its constant pool
- * can be patched to new values.  This provides a hook to pre-resolve
- * named classes in the constant pool to other classes, including
- * anonymous ones.  Also, string constants can be pre-resolved to
- * any reference.  (The verifier treats non-string, non-class reference
- * constants as plain objects.)
- *  <p>
- * Why include the patching function?  It makes some use cases much easier.
- * Second, the constant pool needed some internal patching anyway,
- * to anonymize the loaded class itself.  Finally, if you are going
- * to use this seriously, you'll want to build anonymous classes
- * on top of pre-existing anonymous classes, and that requires patching.
- *
- * <p>%%% TO-DO:
- * <ul>
- * <li>needs better documentation</li>
- * <li>needs more security work (for safe delegation)</li>
- * <li>needs a clearer story about error processing</li>
- * <li>patch member references also (use ';' as delimiter char)</li>
- * <li>patch method references to (conforming) method handles</li>
- * </ul>
