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

             Summary: [findbugs] AsyncSpanReceiver synchronizes a concurrent data structure
                 Key: ACCUMULO-3854
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3854
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.7.0, 1.6.2, 1.6.1, 1.6.0, 1.5.2, 1.5.1, 1.5.0
            Reporter: Josh Elser
            Priority: Minor
             Fix For: 1.8.0, 1.7.1


Noticed this one playing around with ACCUMULO-3853

If the type of {{sendQueue}} is switched to the concrete ConcurrentLinkedQueue instead of AbstractQueue, findbugs will catch this as an error because we synchronize on a concurrent data structure.

{code}
-  protected final AbstractQueue<RemoteSpan> sendQueue = new ConcurrentLinkedQueue<RemoteSpan>();
+  protected final ConcurrentLinkedQueue<RemoteSpan> sendQueue = new ConcurrentLinkedQueue<RemoteSpan>();
{code}

Should trigger some findbugs warnings from the Maven build.
