You need to call isDataReady() on the device before actually attempting to
get any data out of it.
With regards to the error message that you get, it seems that you've
discovered a Javaclient bug. Are you using the latest SVN version? If not,
could you please try with that, and report back either here or on the
java-player-{users,[EMAIL PROTECTED] mailing lists ?
I will look through the code right now to see if there's something I might
have missed.
Update: I just checked the latest Javaclient2 SVN and Stage CVS and it works
fine, so it *might* be a Gazebo problem.
Best,
Radu.
