scripting: no output in plugin's console window

[TobWen]

What steps will reproduce the problem?

1. Load "scripting" plugin
2. Load "jython" using scripting's GUI
3. Switch "scripting" from JS Rhino to Python language
4. Try to run this script: print "Hello world!"

What is the expected result?

The string "Hello world" in the log window of "scripting" plugin.

What happens instead?

No output in plugin's own console log window. Output in JAVA console works, but Normally, people don't see JAVA's console anymore. This might lead into confusion.

Please provide any additional information below. Attach a screenshot if possible.

See screenshot. No error entry in JOSM's log.
