EJB and XI Mappings in P12 (stackOverflowError)

Question

hello,
we have been using the code below to access EJBs from XI mappings (as User Function). In the example we use the SAP sample Calculator EJB.
That code works fine on P11.
However on P12 it throws the exception:
Caused by: java.lang.StackOverflowError

is anybody else using EJBs in XI Mappings?
thanks

Java code  in User Function is:
ClassLoader old_context_classloader = Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread().setContextClassLoader(com.sap.examples.calculator.CalculatorHome.class.getClassLoader() );
// get calculator bean and execute multiply method
InitialContext ctx = new InitialContext();
Object ob = ctx.lookup("sap.com/CalculatorEar/CalculatorBean");
com.sap.examples.calculator.CalculatorHome calcHome=(com.sap.examples.calculator.CalculatorHome)  javax.rmi.PortableRemoteObject.narrow(ob,com.sap.examples.calculator.CalculatorHome.class);
com.sap.examples.calculator.Calculator calc=calcHome.create();
return ""+calc.multiply(3,4); // result should be 3*4 = 12
catch (Exception e){
throw new RuntimeException(e);
finally {
                                                                                Thread.currentThread().setContextClassLoader( old_context_classloader );
