If you checkout the latest MC project and try to run the classloader-vfs
tests it tells you can't create VFS files. This is because it doesn't recognise
the vfsfile: protocol (even though it has been added to the system properties).

This issue is specific to Maven, the tests work fine in the Eclipse.

I tried to debug this before, but I couldn't work out the cause,
because if I added a modified version of the URL class (with extra debugging)
to the bootstrap classpath I couldn't reproduce the problem.

The class from Sun's src.jar doesn't match what's in the JDK. ;-(

I ended up hacking the test using reflection and setAccesible(true)
to set the vfs url handler manually on the URL object.
But I don't want to do that here, the construction of the VFS files
are not in a test in this case, they are in real code.

I'm guessing this has something to do with the way Maven is playing
with the classloaders?
