 I have identified all of the places I believe this needs to be done.

I had no idea that bash's exec built-in allowed for this. Kind of cool.
Two question/comments:

1. You can pass any dummy argument to the JVM in order to do
   things like ps | grep if you just want to look for your process
   in the process table. Is there some compelling reason to replace
   "java" with "foo" in the process table? Example:

   CATALINA_OPTS=" ....  -DmySearchString ..."

   Then you can do "ps | grep mySearchString" and find it.

2. This will only work for bash, not for other shells. In order for any
   patch to be accepted, you'll have to include a test to determine
   whether bash is the current shell.
