JRI/rJava/JGR have their own mailing lists, and it would be better to
ask there.
But there was a rJava update this morning, and it is consequently
little tested. (I know for example that 64-bit JRI will need furtehr
work.) It may be that other things also need an update (like the JGR
stub).
So do ask those who know for sure -- they don't read this list.

Since upgrading to 2.12.0, I'm having trouble getting the JGR to start under
Windows 7, but I'm not quite sure what's happening.
When I try to run the JGR.exe stub, the dialog says can't find Java R interface
jri.dll. As nearly as I can tell from a Google search this is to be a part of
the rJava package which seems to load fine with the library(rJava) command from
the Windows R GUI. Indeed the required .dll is sitting in
C:\R\R-2.12.0\library\rJava\jri as expected. I must admit that my
understanding of Java stubs is limited, and I don't know why this stopped
working with the upgrade.
My ultimate goal of was to run the Deducer package which ironically runs fine
from the Windows GUI despite recommending that I use JGR instead. Any hints
how I recover the use of JGR?
Thanks,
Rob
