Exceptions that implement IDLEntity are not mapped to IDL
correctly, and are not handled correctly by stub and tie generation.

In IDL, these are being treated as boxedIDL types, which is incorrect.
They should be mapped to the original IDL type.

In the stubs and ties the following changes are needed:

In the stub, change:

  String id = in.read_string();
  if (id.equals("IDL:org/omg/boxedIDL/test/ex1Ex:1.0")) {
       throw (ex1) in.read_value();
  }

to:

  String id = ex.getId();
  if (id.equals(ex1Helper.id())) {
      throw ex1Helper.read(in);
  }

In the tie, change:

  String id = "IDL:org/omg/boxedIDL/test/ex1Ex:1.0";
  org.omg.CORBA_2_3.portable.OutputStream out =
      (org.omg.CORBA_2_3.portable.OutputStream) reply.createExceptionReply();
  out.write_string(id);
  out.write_value(ex);

to:

  out = reply.createExceptionReply();
  ex1Helper.write(out, ex);
