Hmm. Didn't think that such an extension could cause that many troubles.

There is a better and simpler solution: If a terminating Tomcat instance
would return some special value (e.g. System.exit(0)), this value could
be used by the existing scripts to just start the server again. E.g. for
the "start" command in catalina.sh and catalina.bat:

That's all! Now, there's "just" the Tomcat-internal stuff left, that
triggers the System.exit(0) ;-) What about new /manager/reboot and
/manager/shutdown commands?
