The increase in the minor GC times with jdk7 is due to the fact that in jdk7 Intern strings and Class-statics were moved to the Java Heap from the PermGen, and these Intern strings and Class-statics are also collected as part of the young generation collections. That causes increase in the minor collection pauses.
There is a debug option 'JavaObjectsInPerm' which can be used to revert the above change and with this option enabled intern strings and class statics get allocated into the PermGen again.
