Description

If you have perm gen settings defined in bin/setenv or elsewhere in your environment, you'll see the following harmless but annoying message when starting Karaf on Java 8:

[janstey@bender apache-karaf-4.0.1]$ ./bin/karaf
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128M; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256M; support was removed in 8.0

We should not try and set these when Java version is >= 8.
