UrlSet excludePaths() method throws a nullpointer exception if the pathString argument is null
----------------------------------------------------------------------------------------------

                 Key: XBEAN-92
                 URL: https://issues.apache.org/jira/browse/XBEAN-92
             Project: XBean
          Issue Type: Bug
         Environment: IBM JDK 5
            Reporter: karan singh malhi
            Priority: Blocker


With IBM JDK 5, when we try to get the system property java.endorsed.dirs, it returns null.  This is a critical issue as it prevents OpenEjb from starting 

In UrlSet, the following method will lead to a NullPointerException:

    public UrlSet excludeJavaEndorsedDirs() throws MalformedURLException {
        return excludePaths(System.getProperty("java.endorsed.dirs"));
    }
This is because the excludePaths() method assumes that the pathString argument is always non-null.
   public UrlSet excludePaths(String pathString) throws MalformedURLException {
        String[] paths = pathString.split(File.pathSeparator);
        UrlSet urlSet = this;
        for (String path : paths) {
            File file = new File(path);
            urlSet = urlSet.exclude(file);
        }
        return urlSet;
    }
