I upgrade a ZEN 4 to a 6.5 in a pure windows environment and I have a problem with Novell Inventory Services. When I start the service and watch the Novell ZEN inventory information windows I have the error...

Error occurred during initialization of VM
java.lang.NoSuchMethodError: java.lang.Thread.holdsLock(Ljava/lang/Object;)Z

the server is a 2000 sp4 with eDir 873 and all the stuff that came with ZEN 6.5.

Any thoughts?
