Prior to this update, the Java Virtual Machine (JVM) G1 garbage collector did not collect interned strings. As a consequence, the JVM sometimes terminated unexpectedly due to running out of memory when using large heaps. With this update, the garbage collector has been fixed to collect interned strings properly. As a result, the JVM no longer crashes due to this bug.

A customer hit the issue of JDK-8180048, in which interned strings are not garbage collected with G1 and resulting OOME in native area. The bug is still in progress as of 2017-05-11.

rhel-6.9 has been released so setting to rhel-6.10.0?

Comment 3 Osamu Nagano 2017-05-17 00:07:10 UTC
Right, the flag is rhel-6.10.0.

Comment 12 Andrew John Hughes 2017-07-05 02:17:45 UTC
Backport is complete and in RHEL 6.10. Waiting on approval for z-stream.

Comment 14 Osamu Nagano 2017-09-07 01:10:55 UTC
Thanks. I got the fixed package on RHEL 6, which is build by bug #1468473.

BTW, I believe this ticket is for the next minor release of RHEL 6. Is the same fix to be included in the next minor release of RHEL 7 as well?

Comment 15 Andrew John Hughes 2017-09-20 15:54:57 UTC
It needs the same bug process. I see you've opened bug 1490260 now to kick start that. I'll start chasing acks.
