I see intermittent pauses in our application where the sync time for a safe point is high.

2015-07-27T03:05:18.478-0600: 734.948: Application time: 4.1685198 seconds vmop [threads: total initially_running wait_to_block] [time: spin block sync cleanup vmop] page_trap_count 733.780: no vm operation [ 343 0 0 ] [ 0 0 1168 0 0 ] 0 0
2015-07-27T03:05:19.647-0600: 734.949: : Total time for which application threads were stopped: 0.0012189 seconds

This leads to a few timeouts as the latency desired is ~100ms. I want to know how do I debug the high sync time. Can I get a debug build for jdk8 or any other way?

updating the jdk to 1.8.0_45 build helped reduce the high safepoint sync time. Thanks. – nihar kawli Aug 12 '15 at 08:03
