What is in System.getProperties(), just before you create the PythonInterpreter, *in your Confluence plug-in*?

From what you write, I am not sure this is what you have looked at.

You can see from the output of jython --print that we define some properties (in the -D... switches). In 2.7.x we use these properties to tell Jython where it is installed. In 2.5.3 Jython tries to work it out, but it wasn't reliable for everyone.

My guess is that you need to set some of the same values up for your plug-in. You can do this either in the java command that launches Confluence, or later in the application/plug-in.
