RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Text:	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.	Story Points:	---

Comment 2 Andrew John Hughes 2017-05-16 16:57:11 UTC

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.
