> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.5.0, 1.5.1, 1.5.2, 1.6.0, 1.6.1, 1.6.2, 1.7.0
> Reporter: Josh Elser
> Priority: Minor

>

> 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.
