Threads doesn't get destroyed

When diameter requests get timed out, it tries to destroy the thread group,
(concurrentFactory.getThreadGroup().destroy(); in 
org.jdiameter.client.impl.controller.PeerTableImpl)

This line Throws java.lang.IllegalThreadStateException and thread group is 
stile alive. So there are lot of unused but not destroyed threads.
As a result we get many
java.lang.OutOfMemoryError: unable to create new native thread
errors after some time.

1.5.1 Final on Linux

Part of the error we get as follows ...
