Hi Julien,

In python, we have

   %exception {
     try {
       $action
     } catch (const std::out_of_range& e) {
       SWIG_exception_fail(SWIG_IndexError, e.what());
     } catch (const std::exception& e) {
       SWIG_exception_fail(SWIG_RuntimeError, e.what());
     }
   }

in wrap_pyBase.i, to customize the exception handling.

I can't find anything similar in Java directory.

Maybe you should try to add the same kind of customization in  
wrap_javaBase.i or in java.i?
(BTW, those two files should be merged in the future.)
