[If you only installed RHQ 4.11 to a fresh, empty DB (i.e. did NOT upgrade from an older version) you may disregard this email]
I documented this in the release notes:https://docs.jboss.org/author/display/RHQ/Release+Notes+4.11
The BZ is here: https://bugzilla.redhat.com/show_bug.cgi?id=1095970
There is a bad sequence that gets created during an upgrade. You need to immediately rename the sequence after you upgrade.
The release notes has the SQL you need to run after the upgrade is complete.
Sorry for the inconvience. Mea Culpa, I should have caught this before the release.
