To help users out if when the -force option doesn't seem to be working warn them that CATALINA_PID needs to be set. This isn't mentioned in the catalina.sh help. As at the moment if you attempt to call catalina.sh stop -force without CATALINA_PID it silently ignores the -force option.
Created attachment 17371 [details] Patch to add a warning to catalina.sh when using stop -force without CATALINA_PID set
Good patch, applied in time for 5.5.17. Thank you.
