Purpose of IF statement in run.conf

[jelevy01]

The following statement is in run.conf

#
# Specify options to pass to the Java VM.
#
if [ "x$JAVA_OPTS" = "x" ]; then
 JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
fi

Can someone tell me what is the purpose of the if statement? I assume it's trying to detect if people are passing in via the command line memory settings and therefore not use the ones configured...

Is there any other purpose?

Yes, that's correct.
