---------------------------------------

             Summary: GridCacheMvccManager.contextReset() generates garbage.
                 Key: IGNITE-2234
                 URL: https://issues.apache.org/jira/browse/IGNITE-2234
             Project: Ignite
          Issue Type: Sub-task
          Components: general
    Affects Versions: ignite-1.4
            Reporter: Vladimir Ozerov
            Assignee: Vladimir Ozerov
             Fix For: 1.6


GridCacheMvccManager.contextReset() method operates on a thread-local LinkedList. Only two operations are used: "add" and "getLast".
Once cache op is finished, it is reset - new LinkedList is created.

Proposed solution:
1) Use TLS (array + index) instead of LinkedList;
2) Reset = (set index to 0) + (nullify all previous elements). The latter is needed because GridCacheMvccCandidate migth contain references to cache entries.
