Description Jaikiran Pai 2013-08-20 06:45:16 EDT

https://issues.jboss.org/browse/WFLY-1906 fixes an issue in the standalone.bat file to remove the -XX:+TieredCompilation JVM option. This option was removed from standalone.sh long time back since it was considered to be a performance problem https://issues.jboss.org/browse/AS7-4547. It however, stayed around in the standalone.bat as an oversight. Some users have noticed that this is causing problems in real environments https://community.jboss.org/message/833173#833173 when using EAP 6.1.

Comment 5 Aaron Ogburn 2013-08-21 14:46:44 EDT

Per http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8008938, some JDK releases may even have tiered compilation enabled by default. We don't want a JDK default setting to lead to those performance issues either so setting -XX:-TieredCompilation instead in the .bat and .sh scripts to override any potential JDK level defaults may be the best option.

Comment 7 Petr Kremensky 2013-09-18 02:21:52 EDT

Verified on 6.2.0.ER1

Comment 13 Dimitris Andreadis 2013-10-24 14:27:55 EDT

Assigning jpai@redhat.com EJB issues to david.lloyd@redhat.com. Please re-assign to Cheng or others as needed.

Comment 14 Russell Dickenson 2013-11-20 21:25:55 EST

Release notes text added, to be published in the JBoss EAP 6.2.0 Release Notes document.

Comment 16 Carlo Marchiori 2015-10-21 03:35:34 EDT

I think this problem should be reported to Oracle, because it's a serious bug of their JVM.
