Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Description James Livingston 2013-07-09 22:53:49 UTC 
There is a JVM crasher bug which is affecting code using Apache commons HTTPClient. A reproducer is available at https://github.com/rholder/jvm-loop-unswitching-bug.


I believe that the crash has been reported upstream into the Oracle Java bug database, but I cannot find a reference to it. It affects both Oracle Java and OpenJDK.



To reproduce download the code from https://github.com/rholder/jvm-loop-unswitching-bug, then run "./gradlew build". JVM crashes will occur during the test.

As noted on the github page, adding -XX:-LoopUnswitching stops the problem occurring.

the next release of Red Hat Enterprise Linux.
