Yes this has been discussed. IMHO it is important to be able to test
proposed changes to the Java fred code efficiently, especially for load
management changes. There have been *many* hacked-up simulations, all of
which are out of date and no longer useful.

Running Java inside NS2 might be possible but would be dramatically
slower. It only makes sense for really low level simulations where the
detailed properties of the underlying IP network matter. That's not my
main concern here. I want to show that load management works, that The
Patch breaks it unfairly, and ideally demonstrate a proposed solution. I
want to make it possible to test changes to routing and load management
efficiently but with the actual code.
