Today's quiz is inspired by the free Chapter of Joshua Bloch's Effective Java, 2nd Edition available from InfoQ.

Somebody internal to Sun is attempting to make JavaFX not fully Open Source. That's the only conclusion that I can draw from the conversations went on in the open source openjfx-compiler project mailing list recently. Here's just a sampling of the goings-on today: Shannon Hickey <Shannon.Hickey@Sun.COM>: The javafx.ui runtime in...

And on Tuesday's session, I heard Danny Coward talking about new features for Java 7, which, BTW, is scheduled for Summer of...
