May not be a specific message if you do this.

synchronized(myNotYetClusteredVar){
        myClusteredVar.set(value);
}

Is there a specific message/exception for that? If so, no, I'm not
running into that. It seems that monitorenter and monitorexit codes
are simply not done in a complex structure with try-catch-finally and
nested synchronizations. Don't know the exact details yet, but I
thought I'd inquire already at this stage in case anything in this
direction was already known?

Are you running into the thing where you are synchronizing on the object
before it becomes shared in the big lock case?

Hi all,

I'm trying to track down some weird behavior that keeps popping up
through the monkeys for the RIFE continuations tests. I've before
already stumbled into unexpected behavior when TC has to lock on
synchronization blocks that are nested at various levels and I worked
around it by splitting the code blocks up in various parts (which
isn't ideal). Before I go any further in trying to isolate it, I was
wondering if there are already known problems with this or specific
situations that are unsupported?

Just to give a taste for what I'm talking about (please don't judge
the horrible length of this method, it kinda grew over time, I never
get 'round to refactoring it):

http://rifers.org/fisheye/browse/rifers/rife/trunk/src/framework/ com/uwyn/rife/engine/ElementContext.java?r=3791#l243

There are several synchronized blocks there on mElement. If I remove
them all and do one big synchronized block on mElement for the entire
method, I get UnlockedSharedObjectExceptions on objects that are
clearly inside the lock (for instance at mRequestState.clearRequest()
in the finally block, line 826).

Thanks for any insights and help,

Geert
