>> Please review this small fix for JDK-8266496.  The fix changes WBIsKlassAliveClosure.do_klass() so that when it compares the specified name with the name of a hidden class, it truncates the hidden class's name at the first '+' character before doing the comparison.  This should work except in the rare case when the pre-mangled hidden class name contains a '+' character.
