[R] R 2.12.0 and JGR

[Prof Brian Ripley]

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.

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.
