The current persistence backend persistence works but is currently flawed. There are too many possibilities for timeouts and missing backends. One example is components/services/src/main/java/org/openengsb/core/services/internal/ConnectorManagerImpl.java; remove the thread and run the "regular" openengsb. This will lead to endless loading times for the services. This is some basically issue somewhere down there which have to be fixed
I'm not sure right now if this is really a 2.0.1 because it may required a little bit greater changes...
