Method without parameters in valuetype declaration is error

The following IDL generates the error:

[idl2java] IDL to Java Compiler, Copyright (c) 2002-2004

[idl2java] there are errors...

The IDL file has been attached. The part of the IDL
causing the problem is:

valuetype MofState {
public Object origin;
public string id;

factory create ();
factory create_with_id ( in string id );
factory create_with_origin ( in string id, in Object
origin );
};

When I insert an in Parameter in the the create()
method, everything works. But that's not what it should
be.

I'm using JDK 1.4.2_07 on Windows XP (SP2).
