Exception just adding an HSV filter

[cpeppler01]

trafficstars

I had previously downloaded and installed the most recent wpilibpi image, flashed it, attached a webcam and booted it. I setup a light and a target, and was able to view the image in realtime via the browser, so network and wpilibpi seem to be working fine.

I downloaded GRIP and installed it on a dev computer. I started it up, and used the http: version with the following string: http://wpilibpi.local:1181/stream.mjpg

I click on the image icon, and the image stream appears in GRIP, in real time, frame rate is high. All is good.

Following the tutorial, I add an HSV filter node, connect the output from the raw image to the HSV filter node, and immediately, the framerate drops, and the processing loop goes up to almost a second...and soon this:

Here is the java stack trace I received: Thread[JavaFX Application Thread,5,main] threw an exception
