Busy wait

Reports calls to java.lang.Thread.sleep() that occur inside loops.

Such calls are indicative of "busy-waiting". Busy-waiting is often inefficient, and may result in unexpected deadlocks as busy-waiting threads do not release locked resources.

Example:

class X {
   volatile int x;
   public void waitX() throws Exception {
    while (x > 0) {
      Thread.sleep(10);//warning: Call to 'Thread.sleep()' in a loop, probably busy-waiting
    }
  }
}
