In Favorites tab, empty *.java files containing no classes look like they do have some -- an expandable node is shown there in the JTree. After a nouse click, the node diappears. [200508111800, JDK 1.5.0_05 b03 fcs, solaris 10 / sparc]
This is reproducible also in projects tab and also expanding methods/fields node works similiary. Of course, it should be better detected, if there exists subnodes and indicate it properly. But this will cause some performance problems. Consider there are many files in your folder. When you expand folder (package) node, all the file has to be checked for class existence. It takes some time. Price for fixing this issue is too high. So suggesting to close as WONTFIX or lowering priority. Opinions?
After a discussion with other team members, we decided to close it as WONTFIX. Issue is valid, but the effect is too small and performance regression to high. And there isn't even any chance to fix it without huge time consuming operation in the future.
Ok, marking as verified.
