>             Project: Ignite
>          Issue Type: Bug
>          Components: data structures
>    Affects Versions: 2.1

>            Priority: Critical
>
> Current semaphore implementation, {{GridCacheSemaphoreImpl}}, has inverted 
> method semantics: {{acquire()}} releases the permit and {{release()}} 
> acquires it. Also, debug-level method {{availablePermits()}} returns permits 
> acquired so far. This confusing behaviour should be fixed.
> Also, it's worth noting in IgniteSemaphore's javadoc its unbounded nature, as 
> opposed to {{java.util.concurrent.Semaphore}}.
