Diagnosing a deadlock at application startup

Hi,
  I'm experiencing a deadlock while starting my application (Thread
dump taken with VisualVM follows under the signature).
It runs on Felix 1.4.1 and starts bundles with FileInstaller. Several
bundles (about 30 out of 100+ bundles) are Spring DM bundles.

Any hint/trick to understand what's going on or how I can diagnose
better the deadlock?

One thing (workaround actually) I'm trying right now is to organize
startup better; fileinstall is great for development, but I can see
that asynchronous startup of 30+ bundles may be problematic. So I'm
thinking about organizing bundles in different folders with different
startup level, following the example of Apache Sling.
