The bug 900549 is still present as a known issue in 6.2 release notes even though it was already fixed in 6.1.1. If this bug should be in 6.2 release notes (as it probably wasn't in 6.1.1 release notes), then it should be listed as a bug fix. Also, it only has a placeholder text instead of real description.
On stage and ready for review (Revision 2.0-2): http://documentation-devel.engineering.redhat.com/docs/en-US/JBoss_Enterprise_Application_Platform/6-Beta/html-single/6.2.0_Release_Notes/index.html
