All C code in JGR is GPL. Tha Java parts talking to R directly (JavaGD, 
Rengine) are, too. From what you posted here this seems to be 
sufficient. As of the other Java code, well, that is a good question - 
I guess we have two purely practical reasons for not-GPLing it ATM: one 
is that we have to check whether we're allowed to do so and the other 
is that we still want to incorporate some major changes until the 
official release (I'm not that much worried about the GUI itself but 
the other parts). I'm sure the licensing issue will be sorted out 
before the official release.

A side note: with xGD and a slightly modifiied JRI it is possible to 
use *any* (incl. commercial) application with R as backend (as it's 
even now legally possible with Rserve), so I don't think this is an 
issue anyway (at least for JGR).

Cheers,
