> When using ThreadSafeClientConnManager and developing with Jetty using
> auto-redeploy feature eventually I run into a PermGen out of memory
> exception. I investigated with YourKit 8.0.6 and found a class loader
> circular reference in RefQueueWorker. Not really sure what I was doing I
> made the refQueueHandler non-final and nulled it in the shutdown method of
> RedQueueWorker. I don't seem to have the problem any longer with circular
> class loader references.
