This is not an error generated by the shell, rather stderr. The file
runLime.sh obviously runs some java code which is encountering an
error. This is probably due to some assumptions made by the .sh when it
is run, like establishing a $CLASSPATH based on the directory '.' which
it assumes is '/opt/limewire', (e.g. CLASSPATH=../lib/SomePacakge.jar)

The wonderful thing about the shell env is that you can attack such an
issue like 34 ways. One of which would be to make an alias that
contains two commands one line separated by ';', e.g. cd /opt/limewire;
runLime.sh
You can then simply call the alias.
