Fix java class differing only by case

Fix java class differing only by case

OSX and Windows cannot handle files with names differing only by
case.  When these files are present in either there's a constant
unfixable change viewable in git status and git diff.

Since this code can be run and compiled on both platforms
names different only by case should be avoided.
