if $CATALINA_PID points to the file that has invalid content
the following will be shown:
ERROR: Process ID list syntax error.

The code should actually be
ps -p $PID > /dev/null 2>&1
if [ $? -ne 0 ]; then ...
This is to be consistent with the remaining of the tests
and to not get junk from the ps output in case of failure.
