Andrey Davydov commented on FELIX-6243:
---------------------------------------

When FelixConstants.RESOLVER_PARALLELISM is exactly one, Felix object not collected by GC too, but I can't understend why. JvisualVM says that it don't see GC root for Felix object =(((

> Tested on java8.
> Felix object creates StatefulResolver and then  StatefulResolver  get link to Felix. 
> StatefulResolver creates Executor in getExecutor() using nested class as ThreadFactory (when FelixConstants.RESOLVER_PARALLELISM greater then 1)
>  
> So every thread in Executor has link to Executor
> Executor has link to ThreadFactory
> ThreadFactory has link to StatefulResolver, because it is nested
> StatefulResolver has link to Felix
>  
> And it is the way from GC root to Felix and GC can't collect Felix after Felix.stop() and all external refs to Felix cut.
