When I fall back to 2.7.4 I can get it to fail reliably. I tried increasing the thread count and the number of threads to add more stress and was not able to get it to fail. I also did a quick review of your change and it looks good, it directly addresses the issue I was seeing. Thanks! I'm surprised you weren't getting the failure before your patch. Were you able to see the failure against 2.7.4?

I didn't get failures but my experience of other similar incidents is that machine, OS, and java version can all play into the probability a test failing. Usually once it is seen to fails, it often/always fails, but it will run clean on another system on the same code. Hence, they sometimes only get solved by code analysis of possible causes. With that positive confirmation, I'll close this JIRA. Thanks.

I had ended up doing a pre-emptive prepare and all was well for a while, as long as you don't need to trigger a new dynamic prepare in a multi-threaded use case. It turns out however that removing anything from the model triggers the need for the prepare and my 'static' model wasn't perfectly static. Back to occasional deadlocks. I've tried this in 2.7.4 and it is still a current issue, reviewing the code further and I'll post back if I find something.
