[R-sig-Debian] JGRError.log on Ubuntu

[silvio]

Good morning,
I installed R and JGR following this guide 
(http://edtechdev.wordpress.com/2009/03/21/installing-r-and-jgr-in-ubuntu-intrepid/#comments). 
Everything works but I noticed that my cpu is completely used by a 
process called "java" (which is JGR) even if I am doing nothing..

In the JGRError.log it continues to add the same lines. See the file 
attached herewith.

Someone can help me? Thank's a lot. Silvio
