From Joe McGlynn below. Problem also reported by Stephen Fitch on same day.
I’m not saying we need those demos, but if we provide a demo it needs to work properly.

From http://docs.oracle.com/javase/tutorial/uiswing/examples/misc/index.html, OS X

1. All links just download the .jnlp, you have to manually open the file to launch it

2. Demo #1, AccessibleScrollDemo launches but has a functional bug (toggling in/cm doesn’t update the in/cm legend…)

3. Demo #2, ActionDemo launches, but throws errors in the UI when you try to click buttons (due to missing resources)

4. Demo #3 is just source code, I didn’t try it

5. Demo #4 “Diva” crashes
com.sun.deploy.net.FailedDownloadException: Unable to load resource: https://docs.oracle.com/javase/tutorialJWS/samples/uiswing/DivaProject/DivaProject.jar

6. Demo # 5, FieldValidator crashes

I gave up at this point...
