You've also got to rebuild the bank.jar to make the test pass.

It looks like the problem is because EJBContainer::isBusinessMethod() is returning false
when EJB3InterceptorsFactory invokes to see if it should apply interceptors.

But I also see this return false when the test passes? And I haven't
figured out why the test passes only when I rebuild the jar?????

Also this code looks wrong to me. Since it doesn't take into account Covariant
return types. It should be testing whether the return type is assignable
not equal.

  |             return false;
  |          Class[] params1 = method.getParameterTypes();
  |          Class[] params2 = other.getParameterTypes();

  |                   return false;
  |             }
  |             return true;
  |          }
  |       }
  |       return false;
  |    }
