Serious testing in progress

Due to bug [ 1172701 ] Fix for empty if delets good code (see http://sourceforge.net/tracker/index.php?func=detail&aid=1172701&group_id=132036&atid=723729\)
I've decided that I definitely needed some real good testing on this project, that's why I'm not working in any new features, but rather hacking jdt tests suites to get a good plugin for testing quick fixes.

Please report any problem you find, so I can get to this, as soon as I get some tests working, doing some extensive testing will be a matter time only.
