The JNLPCachedJarURLConnection.getJarFile() file is failing for 5u16. A null reference is returned in this case. This is causing jaws applications to fail. See comments for more information.

EVALUATION One solution would be to use code funtionality similar to that used in 1.4.2

WORK AROUND this would be to obtain the inputStream via a different call : InputStream is = cl.getResourceAsStream("testfile");
