Or maybe the PIT was just started before the fix for JDK-8062735 was in?
Pit started on november 7, and bug was closed on november 6. It should be i=
n, but mayvbe it was not?

Subject: PIT failures in jmap: Unable to deduce type of thread

Hi,
Many tmtools/jmap and tmtools/jstack tests fails in PIT.
Below is a typical stack trace.
My guess is that this is the same thing as last week about serviceability n=
ot recognizing a new compiler thread.
https://bugs.openjdk.java.net/browse/JDK-8062735

Tests only fails on Mac.
Does anyone know what the problem is?

Thanks,
Mattias
