I'm experiencing a similar problem, though since it occurs at a different 
place in the source code, I'm not sure if it's a different bug or just in 
some slightly different version of NetX where stuff has been moved around.

Either way, I fixed the NPE I was having with the following small patch:

--- icedtea-web-1.3.1.orig/netx/net/sourceforge/jnlp/runtime/JNLPClassLoader.java
+++ icedtea-web-1.3.1/netx/net/sourceforge/jnlp/runtime/JNLPClassLoader.java
@@ -1115,7 +1115,7 @@ public class JNLPClassLoader extends URL
             }

             // Class from host X should be allowed to connect to host X
-            if (cs.getLocation().getHost().length() > 0)
+            if ((cs.getLocation() != null) && (cs.getLocation().getHost() != null) && (cs.getLocation().getHost().length() > 0))
                 result.add(new SocketPermission(cs.getLocation().getHost(),
                         "connect, accept"));

As you can see, it's a very simple patch with no other side effects, so I 
don't think it would hurt applying it until upstream can fix the problem 
for real.
