Hi
Got the same problem here and I’m getting the following information in the JavaRa logs:
Exception encountered in module [JavaRa]
Message: Object reference not set to an instance of an object
at JavaRa.routines_registry.get_jre_uninstallers()
Trying to remove Java 7 Update 11 from a W7x86 client.
It works when I run it through the GUI but that wouldn’t be possible to use when uninstalling through a SCCM-deployment 🙁
