Ubuntu patch for JVM-6900441

Asked by Andreas Wundsam on 2014-02-28

I am working on floodlight. We've recently been bitten by Bug JVM-6900441 of the JVM (http://bugs.java.com/bugdatabase/view_bug.do?bug_id=6900441), which causes basically all scheduling primitives (Thread.sleep, ScheduledExectuorService.schedule, Object.wait, even Unsafe.parkNanos etc.) to hang when the system clock (wallclock) of the OS is set back.

The fix is in jdk7u master, but not in the currently released version 7jdku51, nor the current ubuntu version 7u51-2.4.4-0ubuntu0.12.04.2. I have extracted the patch from the jdk7u master ( https://gist.github.com/andi-bigswitch/9220407) and put up a PPA with a patched version (https://launchpad.net/~floodlight/+archive/openjdk-patch).

I was wondering if the Ubuntu maintainers are interested in releasing a Ubuntu patched version with this fix applied? It seems like a pretty serious bug that may affect other users to.
