Shell script to restart a certain process if it is not responding

I need an java application to run 24/7 on my mac. Unfortunately the JVM process sometimes gets stuck and thus the java application does not respond anymore.

Is there a possebility to detect if a given process has crashed (or at least is not in a proper running state) and restart this specific process subsequent?

I found

ps aux|grep java

which lists the java process (/usr/bin/java)

Now I need to know how to watch the process state codes and how to restart this particular process in e.g. a shell script.

BTW, the process state is T which means stopped as far as I know.

EDIT: Unfortunately four suggestions didn't work on my machine. I configured an global agent and the jar is starting properly but the process still fails after a certain period of time. Strangely enough the process in activity monitor is not marked as not responding, whereas the context menu of the dock item does (see figure)
