-----------------------------------------------------------------
as I understand during tests, problem is actual when MSSQL jdbc drivers run
inside my custom bundle. For all other bundles in our app everything works
fine. So it is my problem.
But I think, that reafactor ThreadFactory from nested to outer class is good
idea anyway and it will be good to shutdown ThreadPool Executor during Felix
stop. It make Felix collectable 60 seconds early, it is good for test routines,
when felix start/stop repeatedly for every test.

> Key: FELIX-6243
> URL: https://issues.apache.org/jira/browse/FELIX-6243
> Project: Felix
> Issue Type: Bug
> Affects Versions: framework-6.0.3
> Reporter: Andrey Davydov
> Priority: Major
> Attachments: felix.png
>
>
> 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.
