Description Valentin Mahrwald CLA 2010-07-14 15:43:03 EDT 
Build Identifier: 3.5.2.R35x_v20100126

When stopping a composite framework, the equinox core event thread is not stopped. This appears to happen as a direct consequence of a service listener hook being registered in the composite framework.

The result is that equinox leaks both threads and memory.

Reproducible: Always

Steps to Reproduce:
1.Run the attached test jar in a 3.5.2 build of equinox (source code included)

This is also possible outside of composites.  If a launcher registers a listenerhook with the framework system bundle context then the same thing can happen.  I fixed this by calling a new method that protects against the illegal state exception.
