* <li>Fixed fixURL() because it is to "Unix" centric. Right now the method looks for the last
* part of the JAR URL (file:/...) which should be the JAR file name and add a "/." before them.
* Now this should work for Windows as well (the problem with windows was that after "file:" came
* the DRIVE LETTER which created a wrong URL).
