OK, finally found it. Eclipse does some really nasty URLStreamHandler
tricks. It seems to depend on us NOT trying to find a new
URLStreamHandler when the URL.set() method is called. Kind of makes
sense if the protocol isn't changed. So doing something like:

  if (!this.protocol.equals(protocol))
    {
      URLStreamHandler protocolHandler = getURLStreamHandler(protocol);
      [...]

Gets us a little further.

Then you will hit the fact that we don't have a real nio FileLock yet.
But you can work around that with -vmargs -Dosgi.locking=none

Then we hit:

javax.xml.transform.TransformerFactoryConfigurationError: Factory class
com.icl.saxon.TransformerFactoryImpl not found
   at javax.xml.transform.ClassStuff.createFactory (ClassStuff.java:141)

Since they decided not to automagically include their own XML stuff
since M9... So you need libxmlj or something like xalan added to your
bootclasspath. I tried that, but I now have jamvm crashing. Rebuilding
libgcj with the above patches now. But first some sleep.

Happy Hacking!
