[R-sig-Debian] trouble loading JGR on Debian

[Liviu Andronic]

Dear developers
I am unable to (properly) load JGR on Debian testing. The JGR window
will pop out and R will start up, but it will not perform any of the
JGR specific library() calls (rJava, JavaGD, etc.) and will stuck at
100% CPU while the prompt will be non-responsive. The hack that helped
previously in such cases, accessing Help > About [1], works no more.

All R packages are installed via cran2deb on amd64 platform. This
issue was present on 2.9.2, as it is now on 2.10.0. Below are the
errors that pop up when JGR is started from within R, and further the
sessionInfo().

Could anyone suggest how to make JGR load properly under Debian? Thank you
Liviu

Please use the corresponding JGR launcher to start JGR.
Run JGR() for details. You can also use JGR(update=TRUE) to update JGR.
