The issue is that the cancelation of the timer is not removing its association from the java.util.Timer as the TimerTask.cancel just marks the TimerTask.state as cancelled, but its not removed until the timer actually expires. This was leading to a huge list of transaction timeout objects and the associated object graph. Clearing the TimeoutImpl refs in cancel restricts the transient buildup to just the TimeoutImpl. I don't see a way to immeadiate disassociate the TimeoutImpl from the java.util.Timer internals.
