For example:
journalctl | grep azureus | grep "ERROR: unable to bind" > /dev/null
&& killall -SIGHUP java

More elegant to be able to detect this failure at the attempt to start
the azureus client, do the kill and then retry the start (while
checking for loops). But that mightn't be possible depending on how it
reacts to your attempt to restart it.
