Yes, that is the only message I see.
Upon starting the application, the Console shows this message:
6/26/14 9:42:39.255 AM JavaApplicationStub[1679]: Unrecognized Java VM option ignored:
There are no other messages displayed in the Console. Either after pressing the Upload button or upon quitting the application.
I have the application located here:
/Applications/Utilities Extras/OpenSprinklerUpdater/application.macosx/osFirmwareUpdater.app
Also, have the Arduino application version 1.5.5 and Java for OS X 2013-005.
