> When you create a Thread in C#, JVM creates corresponding thread "Thread-NNNN" which
is visible in jstack. When C# joins this thread, it is not removed from JVM and is kept around.
This means that jstack may show thousands of threads which are not there. Reproducer is attached.
It is presumed that memory will be exhausted eventually.
