The director c++ exceptions are thrown in a helper method instead of in the director overloaded method. This circumvents compiler warnings about throwing exceptions when the method has an exception specification or noexcept. If the exception is thrown, abort will still be called! In Java, the "director:noexcept" typemap can be used to do something else. This typemap should be ported to the other languages too.
