JMC (Core APIs) fails to parse and visualize a thread (possibly VM Thread) in a Application/JVM  running on Java 14. Ths is shown as null in the thread list

 

1) Number of Threads shown in JFR and JMX Console are not same

 

 

 Tried adding the null thread in focus selection then filter other events,  and closing JMC from command line (Ctrl+C) results in a crash.

 

 Also look at : https://bugs.openjdk.java.net/browse/JDK-8190482
