JProbe and J2EE 6.45 - server node waiting for start

Hello,

to profile code on a 6.45 J2EE-Engine i installed JProbe Suite 5.2.3. I used the configtool to add the java parameters for the server node and created a jpl.startup file. But when restarting the server node, it only says 'Waiting for start' and that's it. Having a look at the developer trace in the sapmmc shows that the jvm is not loaded for the server node. All specific changes for the jpl.file regarding JProbe version are done.

What can be wrong?

Regards, Alexander
