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.
The fix was tested with Mach5 tiers 1 and 2 on Linux, Mac OS, and Windows, and tiers 3-5 on Linux x64.
Thanks, Harold
