GapPatternPostProcessor should only rename .java files

[dwerle]

The GapPatternPostProcessor should check if files are actually .java files before renaming them (or more generally check if a match means that the file is to be renamed). The current processor will fail, for example, if both directories are empty and contain a .gitkeep file (will be renamed to .gitkeep.java).
