IIRC I ever faced a similar problem sometime ago. The way I make this happen is by loading a bunch of JARs using ModuleFusion's DirInstaller.
This problem is intermittent, happens about 50% of the time. Should I post a bug report? I see WeakHashMap below... would using ConcurrentHashMap solve the problem? Since it only called by Activator (once per bundle lifecycle?) I don't think there's significant performance hit.. ...
