Thanks Alexey, I need to have a look at the docu to better understand the class loader stuff ... The reason why I am doing this is: - I want users to be able to script additional functionality - if it works as script it could be switched to 'strict Java' mode - and if performance required it compiled into the application. To test I just used the java code of an existing class - which should work In the test code I set up the class path to the compiled classes like HardwareREgistry & EventQueue. Then I source the java class file into the interpreter - I was assuming this would use the same or at least cascaded class loaders.

I'm wondering if this isn't because they are loaded by different class loaders and so com.rabe.proofstepmanager.hardwareregistry.HardwareRegistry and com.rabe.proofstepmanager.eventqueue.EventQueue classes in the constructor signature are not the same for the JVM as their versions loaded as normal class files. Is there a reason you need to source a legal Java class file rather than load its compiled version?
