JRE 8u91 or higher cause performance problems with the GL Video library - specifically: SimpleCapture example doesn't show a texture from USB-attached webcam on Raspberry Pi 2, and TwoVideos example doesn't play two videos smoothly.

This was tested with Processing compiled on the Pi (JDK 8u65b17), and processing-glvideo 2d6de36a33fde3573b335e9a95cc3e380466f328.

@benfry Spent all morning tracking down this regression ... would you mind if I re-spun the ARM tar-ball for 3.1 with this change? (Holding off with the Raspbian image for now)

@benfry I went ahead and updated the tar ball, after realizing that my previous re-spin had the wrong build number (250). So the processing tar ball for ARM is now essentially: https://github.com/gohai/processing/commits/arm-work

Doesn't this have to go after these two lines?

<property name="jdk.update" value="92" />
<property name="jdk.build" value="14" />

Thought properties in ant can only be set exactly once - hence setting it conditionally for the special case ahead of the default. (Most importantly: seems to work :) )

@benfry Is there any place to report/triage issues with JDK releases? A phone number where Larry Ellison picks up, perhaps?

Nah, Larry's on a boat somewhere so he doesn't have to pick up the phone.

But the openjdk mailing lists work for discussion, and then there's a bug reporting system (JIRA-based?) that handles the official things.
