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.

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.
