      Description

        I created a test to reproduce ConcurrentModificationException in BasicDirectoryModel. There were several attempts to fix the problem: JDK-8240690 and later JDK-8307091, JDK-8323670.

        None of these fixes provided a reproducer.

        During code review [1] for JDK-8323670, I mentioned that the problem can be reproduced by my test. After that, I fine-tuned the test. However, it doesn't always reproduce the problem, it's stable enough.
