This looks like a bug in OpenSuse 11.1 to me. The shell is clearly
interpreting a file ending in .jar to be a JAVA file. This is certainly not
POSIX compliant in anyway - or even 'best practice' so should probably be
reported to OpenSuse as a bug. Note the original email suggested it was
fixed in 11.2 so maybe they already realized their mistake.
If we want to avoid having to deal with this with users though then the best
bet is probably just to rename the Run.jar and Run.jarzinski and be done
with it.
I leave it with Dave (who possesses the master copy of the git tree right
now to make this change).
All the best
