Motivation: ThreadLocalRandomTest reveals that ThreadLocalRandom's initial seed generation loop becomes tight if the thread is interrupted. We currently interrupt ourselves inside the wait loop, which will raise an InterruptedException again in the next iteration, resulting in infinite (up to 3 seconds) exception construction and thread interruptions. Modification: - When the initial seed generator thread is interrupted, break out of the wait loop immediately. - Log properly when the initial seed generation failed due to interruption. - When failed to generate the initial seed, interrupt the generator thread just in case the SecureRandom implementation handles it properly. - Make the initial seed generator thread daemon and handle potential exceptions raised due to the interruption. Result: No more tight loop on interruption. More robust generator thread termination. Fixes #2412 |
