I believe that the execution speed in this application between the two languages is not important.

The java libraries, as I would consider them, are still under development. For instance the wrapper for the camera imaq* is mostly missing.

That being said you certainly can still track targets just its a bit harder.

For all intensive purposes you can completely program the robot without issue in java and c++ so it comes down to a personal decision. . .

Which language are you more comfortable with?
