Finally not called -> deadlock

Lamdas and locks do not play nice. See my very long thread here:

Help with reentrant locks - goes wrong somewhere

Folks, I’m hoping someone can point out where by hole is in the code below - Rule: val Functions$Function3<GenericItem, String, ReentrantLock, Boolean> getPosition = [ GenericItem itemBlind, String mac, ReentrantLock fronRoomBlindLock | try{ if (fronRoomBlindLock.getHoldCount() > 0){logWarn("Blinds - Front room", "getPosition - Waiting on other locks. Count:" + fronRoomBlindLock.getHoldCount().toString)} …

I have since rewritten the code to not use lamdas and, while the locks still get hit and do their job, I have yet to have one give me a problem.

See “proof” in this post where it does not lock / hit the finally

Found it!!! I peppered the code with entry and exit debugs. I also put in another cron job which checks periodically if the lock is locked. If it is, I unlocked it. I then left it for a day, trawled through the logs; find the first force-unlock and watch the flow from there.
