Review Comment:
How would we list then ALL threads having locks?

>
> When adapter "gives up" (as it could not acquire required lock), the error
> currently states "how many retries were against which lock". This gives
> information only about failed lock, but lacks the "whole picture".
> Proposed change: in case of lock failure, factory should dump out all lock
> states (may be huge on big builds), as that would allow simpler
> identification of possible problems. All this could be sorted out at "high
> level" (so no need to fiddle with file locks, hazelcast or redisson), but for
> memory constraints it should NOT be enabled by default, this "diagnostic"
> should be turned off by default, but possible by users to turn on if needed.
