Except that RPG doesn't allow object subfields, so the L member can't be defined like(jobject). An object reference is actually an integer, so jint (or maybe better 10i 0) has to be used for that subfield.
The problem with that is that you can't assign an object to an integer or vice-versa.

For example, the following won't compile:
D myint s 10I 0 inz(123)
D myobj s O CLASS(*Java:'java.lang.Object')
/free
myobj = myint;
When you want to call an API like CallVoidMethodA() and the method you're
calling accepts an object as a parameter, how do you pass the object? You
can't use the jvalue array because you can't assign the object to the
integer.
Granted, you could make your own copy of the CallVoidMethod() prototype and specify the exact parameters you want (this is what I've had to do) but it defeats the purpose of having an L member in the jobject structure.
