This may  not be an issue given your other VM opts, but just FYI I
have had some difficulty making the incremental CMS mode perform GC
work sufficiently aggressively to avoid concurrent mode failures
during significant garbage generation.

You may want to give CMS a try in non-incremental mode (i.e., the
concurrent mark phase will be done in one burst, rather than spread
out over time, but still concurrently).
