* DESCRIPTION
* The test does the following in a loop:
* 1. Enters a deadlock involving methodhandles and invokedynamic target and bootstrap methods
* (deadlock is created using both java.util.concurrency.lock.ReentrantLock and
* synchronized() Java syntax)
* 2. Finds that deadlock using ThreadMXBean
* 3. Unlocks one thread to let others go

* To see code that takes more time to safepoint run with:
