Hello,

I actually found the reason for my crashes (old JVM wath in path). If I
remove it from the path the following works (I use jconsole as a sample
Java application to monitor, if you use java.exe -jar instead the -J
has to be removed:

C:\>"c:\Program Files\Java\jdk1.8.0\bin\jconsole" -J-XX:NativeMemoryTracking=detail
C:\>"c:\Program Files\Java\jdk1.8.0\bin\jcmd" -l
