[jira] [Updated] (IGNITE-6043) Fix GridCacheSemaphoreImpl methods semantics

["Andrey Kuznetsov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-6043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrey Kuznetsov updated IGNITE-6043:
-------------------------------------
    Description: 
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}}.
