Comment 1 Curtis Rueden 2014-11-17 14:16:30 CST 
Thank you. This has been an issue for a while now, but no one has had time to investigate. It has something to do with the fact that the JavaScriptEvaluator class (packageless) cannot be modified by the ImageJ Legacy component's Javassist logic, because the class cannot be loaded. Perhaps it's an issue with packageless classes in general -- likely a lurking larger issue.

In the short term, from an end user perspective, the exception is harmless and can be ignored.

I believe this issue was finally resolved a while back. Please reopen if not.
