Adding JMH to the project and running it resulted in an error like the below, also after calling Realm.close():
<JMH had finished, but forked VM did not exit, are there stray running threads? Waiting 24 seconds more...> Non-finished threads: Thread[Thread-3,5,main] Thread[DestroyJavaVM,5,main] Thread[pool-3-thread-1,5,main] at java.base@11.0.10/jdk.internal.misc.Unsafe.park(Native Method) at java.base@11.0.10/java.util.concurrent.locks.LockSupport.park(LockSupport.java:194) at java.base@11.0.10/java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2081) at java.base@11.0.10/java.util.concurrent.LinkedBlockingQueue.take(LinkedBlockingQueue.java:433) at java.base@11.0.10/java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:1054) at java.base@11.0.10/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1114) at java.base@11.0.10/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base@11.0.10/java.lang.Thread.run(Thread.java:834) Thread[pool-2-thread-1,5,main] at java.base@11.0.10/jdk.internal.misc.Unsafe.park(Native Method) at java.base@11.0.10/java.util.concurrent.locks.LockSupport.park(LockSupport.java:194) at java.base@11.0.10/java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2081) at java.base@11.0.10/java.util.concurrent.LinkedBlockingQueue.take(LinkedBlockingQueue.java:433) at java.base@11.0.10/java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:1054) at java.base@11.0.10/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1114) at java.base@11.0.10/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base@11.0.10/java.lang.Thread.run(Thread.java:834)
This could indicate that we do not close all threads correctly and should be investigated. It could also just be some internal coroutine or JMH artifact we have no control over.
