Tried this. Now jBoss exits in the line "String path = loc.getFile();", which 
means that there is no URL for the code-source, which in turn means that it 
should be set. This is only done by the URLClassLoader. Does JDK specify, 
whether this has to be done by the other ClassLoaders as well?

   /**
    * Boot up JBoss.
    *
    * @param args   The command line arguments.
    *
    * @throws Exception    Failed to boot.
    */
   public void boot(final String[] args) throws Exception
   {
      // Auto set HOME_DIR to ../bin/run.jar if not set
      String homeDir = System.getProperty(ServerConfig.HOME_DIR);
      if (homeDir == null)
      {
        ProtectionDomain pd = Main.class.getProtectionDomain();
        CodeSource cs = pd.getCodeSource();
        URL loc = cs.getLocation();
         String path = loc.getFile();
         /* The 1.4 JDK munges the code source file with URL encoding so run
          * this path through the decoder so that is JBoss starts in a path 
with
          * spaces we don't come crashing down.
         */
         path = java.net.URLDecoder.decode(path);
         File file = new File(path).getParentFile().getParentFile();
         homeDir = file.getCanonicalPath();
      }
      props.setProperty(ServerConfig.HOME_DIR, homeDir);
<code continues>

Greetings, Ron.
