Description Jaikiran Pai 2013-08-20 10:45:16 UTC
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.

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.

Verified on 6.2.0.ER1

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

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