         // create window
-        JFrame mainFrame = getMainFrame();
         mainFrame.setTitle(resourceMap.getString("frameTitle"));
         mainFrame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
         mainFrame.setJMenuBar(buildMenubar());

Cal, probably is something more hard to find. I keep working on it

[cal101]

I don't want to spend too much time extracting real test cases for everything. Let's do a first run of the bugs that are easy to reproduce (and to fix) and do a second run for the difficult ones where I can try to extract real test cases.
I don't plan to use the PMD plugin at all but just noticed a thing or two when playing with it.

Ok,

I have fixed some important issues and I think that most of those that you reported are pretty much related. Let's see what happens.

Test case https://github.com/cal101/walkmod-misc/commit/328a3d173d6c7770cac220e474dc852bf3cc60ad

I have created a test for it and it does not break. When I print the source code is exactly the same https://github.com/walkmod/walkmod-pmd-plugin/commit/8781ce698709648f891147e039b542d887d6adca
