ThreadJoinLoop
Thread.join needs to be immediately surrounded by a loop until it succeeds. Consider using Uninterruptibles.joinUninterruptibly.

The problem

Thread.join() can be interrupted, and so requires users to catch InterruptedException. Most users should be looping until the join() actually succeeds.

Instead of writing your own try-catch and loop to handle it properly, you may use Uninterruptibles.joinUninterruptibly which does the same for you.

Example:

Thread thread = new Thread(new Runnable() {...});

Uninterruptibles.joinUninterruptibly(thread);

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("ThreadJoinLoop") to the enclosing element.
