Precisely -- The trivial shell script I wrote actually calls

    cd /opt/JGR-1.3 && java -cp JGR.jar:. -Xmx512m org.rosuda.JGR.JGR $*

as 'java' is handled The Right Way (TM) by Debian's update-alternatives(8). 
However, your Makefile doesn't know that and I was merely pointing out that 
it pasted together a wrong path using the information it otherwise used
rather successfully to build the beast.

Exactly, that would do it !

Thanks,  Dirk
