> Calling JarFinder.getJar() throws an exception if user has a "META-INF/MANIFEST.MF" in
the same directory of the .class specified.
> Jarfinder.getJar() call createJar() that always create a new Manifest and then add all
the files contained in the .class directory.
> To reproduce the problem in a simple way you can create a SimpleClass.java in the same
directory create a META-INF/MANIFEST.MF and then call JarFinder.getJar(SimpleClass.class)
> {code}
