Java 7 build 16 was released last week – see the change list for more info.

Libraries

Stephen Colebourne has posted the 4th design principle, Extensibility for JSR 310, the new Date and Time API.

Swing

There were a couple of articles posted about presentations on the Java 7 Swing frameworks (JSR 296 Swing Application Framework, JSR 295 Bean Binding, etc). See Evan Summers’s presentation and Chet Haase’s presentation at OSCON.

Danno Ferrin posted on some updates to the Groovy layer for JSR 295 based on the recent changes from feedback.

Language Proposals

JVM

Cliff Click from Azul did an awesome nterview with The Server Side which talks about tiered compilation and a lot of other interesting Java stuff. Definitely my favorite read of the links this week.
