UPDATE　Apple サポート：Java for OS X 2013-004 について (Last Modified: 2013/06/24)

先日、AppleはOS X Lion v10.7 および OS X Mountain Lion v10.8 向けの「Java for OS X 2013-004」と Mac OS X v10.6.8 Snow Leopard 向けの「Java for Mac OS X 10.6 Update 16」を公開していましたが、すぐにソフトウェア・アップデートした場合に古いバージョンがインストールされている可能性があるそうです。

（via 9to5Mac）

最新かどうかはターミナルで「/usr/libexec/java_home -v 1.6 -exec java -version」とコマンドを入力し確認できるそうです。最新のバージョン「xM4509」で、旧バージョンは「xM4508」です。

▶ FIXED! 1.6.0_51 in Java 1.6.0_51 OS X 2013-004 & 10.6 Update 16

Hello Java developers,

As of 10:00AM PST today, Apple has revised the "Java for OS X 2013-004" and "Java for Mac OS X 10.6 Update 16" updates to fix a widely reported issue with the original updates that shipped to customers on Tuesday.

The crux of the problem involved dispatching events through sun.awt.AppContexts which were setup incorrectly when the JVM first initialized the AWT. Some impacted applications could work around the problem by changing the order of initialization of these classes, but we believe that we have provided a comprehensive fix with these revised updates.

If you have previously installed the xM4508 versions of these updates you can upgrade to the fixed xM4509 version by manually installing:
(10.7, 10.8+)
(10.6-only)

You can check if you have installed the xM4508 versions by running:
/usr/libexec/java_home -v 1.6 -exec java -version

If you have not installed "Java for OS X 2013-004" or "Java for Mac OS X 10.6 Update 16" already, you should receive this fix automatically through Software Update / App Store.

If you have installed the previous Developer Package, we have posted fixed versions at:

We apologize for the inconvenience this has caused, and would like to thank all of the developers who have brought this issue to our attention.

Thank you,
Mike Swingler
