This is just a silly mistake on my part.  However...  this would not cause 
any problems.  A type O field in RPG (a Java "object") is really nothing 
more than a number.  The actual object itself is stored in the JVM, not in 
your RPG program.  The O field is a "reference" to that object. So the JVM 
creates the object, then returns a number that your program can use to 
refer to the object when it needs to.  As long as the number was correct, 
having "FileOutputStream" instead of "FileInputStream" wouldn't make any 
difference at all.   As long as the correct type is referenced on the 
prototype, that is.
But, anyway, I agree that it's wrong and misleading and I'll update it.

This sounds an awful lot like something that I've already fixed. Since you 
appear to be using an old version of the code, could you please download 
an updated copy?  For the sake of convienience, I've zipped up my copy of 
the code, and placed it at the following link:

Not really, but there was an issue with java i/o exceptions that would 
occur if you don't have at least FDs open in the job.  If you download the 
code above, it makes sure that there are at least 3 open.
The other thing you'll want to verify is that you have THREAD(*SERIALIZE) 
on the H-spec of your program.
