Parsing takes a really long time. SourceForBinaryQuery is slow.

Comment 3 Svata Dedic 2015-07-24 08:53:51 UTC

delegates to j2seplaetform/project.

Comment 4 Tomas Zezula 2015-07-29 16:29:36 UTC

There are 3 things:
1st) The warm up of the global libraries may not work if it's the first call to the SourceForBinaryQuery - fixed
2nd) The LibraryManagers were not cached - fixed
3rd) Extremely slow *monitorenter* instruction - not sure why. The monitor is uncontended or at least no contention visible in sampling. It can be spin-then-park if a small invisible contention exist or biased locking stack annotations or something else. If it happen again I we will need hotspot lock log.
