Artemis broker seems to be leaking memory when creating and deleting temporary queues. Running clients with code like below

try (QueueSession session = queueConnection.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE)) {
      int numberOfTemporaryQueues = 100;
      for (int i = 0; i < numberOfTemporaryQueues; i++) {
        TemporaryQueue temporaryQueue = session.createTemporaryQueue();
        temporaryQueue.delete();
      }
    } catch (JMSException e) {
      e.printStackTrace();
    }

would result in
