OK, thank you for those precisions on JGR license... For me, the more code
will be GPL, the better!
Have a nice day,

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).
