Version 1.4.1

I am running an instance of VisualVM and attaching it to the same application, one time running under Java 8 and later running under Java 10. When running under Java 8 I see the thread state as PARK most of the time. When I run under Java 10, those same threads show up as WAIT most of the time time. I never see PARK used under Java 10.

Is this a bug in VisualVM or does Java 10 never use PARK anymore?
