Description

Currently, the framework completely ignores concurrent access to the same bundle cache and leaves it as a configuration issue. The downside of this approach is that a mistaken configuration could corrupt your bundle cache. We could avoid this by introducing some sort of bundle cache locking protocol using java.nio.channels.FileLock. I think it would be sufficient to simply implement a fail-fast locking protocol.
