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.

java-1.7.0-openjdk-1.7.0.85-2.6.1.3.el6_6.x86_64.rpm  Looks to be the latest OpenJDK7 version available for RHEL6.6.

https://access.redhat.com/downloads/content/java-1.7.0-openjdk/1.7.0.85-2.6.1.3.el6_6/x86_64/fd431d51/package
Comment 4 Travis Rogers 2016-09-12 22:53:48 UTC 
Looks similar to https://bugs.openjdk.java.net/browse/JDK-8028216.
Comment 9 Andrew John Hughes 2016-09-13 17:18:18 UTC 
The latest version is:

java-1.7.0-openjdk-1.7.0.111-2.6.7.2.el6_8

The reported version was released on 2015-01-21, making it four months short of being two years old. Even if we could reproduce and fix this issue, any patch would be against the new version, not this unsupported one.

As is, without a reproducer, my suggestions would be:

1. Try running with -Dsun.zip.disableMemoryMapping=true to see if that makes any difference.
2. As this is a crash in the native zlib library, update to the latest version of that.
3. Update to the latest version of OpenJDK listed above.

https://bugs.openjdk.java.net/browse/JDK-8028216 does look similar and Oracle were equally unable to reproduce this.
Comment 11 Chris Williams 2017-06-07 22:15:30 UTC 
Red Hat Enterprise Linux 6 transitioned to the Production 3 Phase on May 10, 2017.  During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available.

The official life cycle policy can be reviewed here:

http://redhat.com/rhel/lifecycle

This issue does not appear to meet the inclusion criteria for the Production Phase 3 and will be marked as CLOSED/WONTFIX. If this remains a critical requirement, please contact Red Hat Customer Support to request a re-evaluation of the issue, citing a clear business justification.
