Denis Mekhanikov commented on IGNITE-4173:
------------------------------------------
[~vladisav] currently if a node, that exclusively holds a semaphore, leaves,
then another node will not be able to acquire it. This is not an expected
behavior.
Judging by javadoc, semaphores should be released anyway, even if it was the
only node that held the semaphore instance.
