 Description   

PriorityThreadPool states that it cannot throw an exception, but there are several situations where it can (such as out of memory). This causes a crash instead of proper error handling.

Highly likely this is related to MCOL-1037. If a priority thread job throws an exception for any reason it is silently ignored. This means a priority thread could stop giving ExeMgr data silently.

Please do not merge until after 1.1.5 has been released.

For QA: No real way of testing this. I had to hack a bug into a BPP step and use gdb to trigger it to test this.
