This doesn't help on its own because you seem to be dealing with Full
GCs and explicit GC invocations.  The latter result in Full GCs even
with the CMS collector by default.

I think a switch to turn those explicit GC invocations into concurrent
ones has recently been posted, but I can't find the message right now.
