Bug in OpenCMIS causing memory leak

Customer reports that due to apparent bug in OpenCMIS there system becomes unresponsive.

Reviewing memory utilization with JConsole and/or YourKit profiler shows huge amounts of memory being allocated and de-allocated in a short period of time and a lot of time is spent garbage collecting. So much time in fact that the server is unresponsive.

There are many threads that are frozen and look like this (note they are not deadlocked):
