Description

Deadlock issues with SCR: Component operations are synchronized and may run while the bundle lock is held. This may cause deadlocks with the framework (mostly between the PackageAdmin thread and the SCR Component Actor thread).

The problem is that many operations of SCR are called in a bundle listener and cause further operations (while holding Java locks (synchronized)) inside the framework.
