EVALUATION Yes, this issue is reproducible as mentioned in "Description". But, I tried a standalone program - with a class called Window extending JPanel. The print(String) method on such window object can be called. So, it appears this is something specific with demo's scenario. I'd like to defer to this demo bug to update release.
