Hi, Can someone help reviewing this fix?
Besides changing the Provider class to use ConcurrentHashMap in order to reduce the lock contention on Provider.getService() calls, I also changed the security providers in java.base module to register through putService(...) calls. Performance is manually verified and mach5 run is clean.
