I haven't find explicit code synchronize InstanceKlass' content. In SystemDictionary::loadinstanceclass, it uses MutexLocker and this might help.

We don't need to synchronize in TemplateTable::_new because Klass::layout_helper saves the slow_path flag in the least significant bit. If we find that layout_helper is not valid we'll take the slow path and acquire the lock.

That looks OK.

Thanks,

Andrew.
