Project: Community Development
Issue Type: Bug
Components: DSO:L1
Affects Versions: 2.4-stable0
Reporter: Tim Eck
Assigned To: Issue Review Board
We can potentially set the thread context loader to null when
loading/initializing user land classes. Under JBoss (at least version
4.0.5-GA), there is a bug in their in-house fork of commons-loggging.
