-XnoClassGC is now considered (deprecated) according to: http://docs.oracle.com/cd/E15289_01/doc ... m#BABCCBJD

there you can see info about the current Java HotSpot VM Options: http://www.oracle.com/technetwork/java/ ... 40102.html

Then in others words with -XX:+UseClassGC, I save some memory and without consume more memory.

I think it's "-XX:-UseClassGC" (-, not +) if you want to disable it.
