You're assuming that tomcat is daemonizing but it seems the task is running 
with some option that prevents it from forking and leaving the current shell 
(so it's parent ID process is init)

Check startup.sh and make sure the command is run without debug or "no fork" 
or whatever equivalent option tomcat uses. It might be as simple as "write 
output to stdout" and when your shell exits the task dies. (broken pipe)

Hope that helps
