implementing java interface in svg script

[Jeffrey Hau]

Hi,
i have the following ecmascript embedded in a svg document,
function test() { alert("test java.") };
obj = { run: test };
r = java.lang.Runnable(obj);
t = new java.lang.Thread(r);
t.start();
when i run this in batik (JSVGCanvas) i get the following error,
org.mozilla.javascript.EvaluatorException: error instantiating  
(java.lang.RuntimeException: NOT SUPPORTED): class java.lang.Runnable  
is interface or abstract (Inline <script>

however the above script works fine in rhino's shell. Has this feature  
been disabled in batik?

thanks
