Message on each startup of Java after upgrade to 15.04

This PPA is to get Unity AppMenu and HUD support for applications like NetBeans IDE, IntelliJ IDEA, Android Studio etc., as described here. So, unless you want this you can delete the package using sudo apt-get remove jayatana (and as the stackoverflow thread suggests, removing /usr/share/upstart/sessions/jayatana.conf and restarting your computer). I am not sure if this is by default installed by 15.04 because it is not listed in the author's repo.

Why does this message appear?

Apparently it's reporting that the environment variable JAVA_TOOLS_OPTIONS has been set.

Does anybody else observe this?

Yes, I see it and am annoyed by it as well.

Can it be disabled?

A couple of sites suggest uninstalling jayatana, but I'm reluctant to do that since I don't really know why Ubuntu installed it in the most recent release.
