> 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.
