Good advice.
Perhaps I was reading my own motivations into the OP.
I've had occasion to be dissatisfied with the packaging of "third party" 
and even my own code.

I think I may not have precisely understood the process described by the 
OP.
Referencing the two paragraphs above.

Beginning with "I have a Java program ...",
I can read this several ways:
a) I snagged some binary class files from another project and packaged 
them in a jar,or
b) I built and jar packaged another project using it's own build process,or
c) I built (perhaps a subset) of the classes from another project and 
packaged them in a jar.

Beginning with "But now we decided ..."
I suspect here is where the process breaks:
It sounds like:
I am attempting to build (perhaps a subset of) another project using my 
own build process.

If I look at for instance Javolution library, their build process 
includes a non-standard text substitution step to include or not Java 
generics.
