When a transactional cache (local, xa or xa_strict) is configured with a short TTI or TTL there’s a high probability to run into a deadlock.

Attached example app reproduces the problem.

The deadlock seems to be caused by a ‘lock leak’ which can happen when an inline eviction fails b/c of a transaction timeout.

Surrounding the eviction code with a try / finally block releasing the lock in the finally seems to solve the issue.

The proposed patch solves the issue and was confirmed by the user.

Fixed applied in trunk and 2.4.x branch.
