The Java 1.6.0_51 update released today breaks MATLAB 2012b and below. You can open the program but it does not register any mouse or keyboard interaction until the window is resized.
Is there a patch coming?
This issue has been fixed.
The was an issue in the Java security updates that Apple released for Mac OS X (as mentioned above). These updates install Java 1.6.0_51 and the exact build number looks like this (ending with M4508):
Java™ SE Runtime Environment (build 1.6.0_51-b11-456-10M4508) You can check if you have installed the xM4508 versions by running any one of the following commands on the Terminal of your Mac OS X:
/usr/libexec/java_home -v 1.6 -exec java -version
If you have previously installed the xM4508 versions of the Java updates you can upgrade to the fixed xM4509 version by manually installing the following update:
Mac OS 10.7.x and 10.8.x: ================
Mac OS 10.6.x: ================
Confirm that you have the updated Java version by executing any of the above two commands. The exact build number looks like this (ending with M4509):
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-10M4509)
updates already (ending with M4508), you should receive this fix (ending with M4509) automatically through Software Update / App Store.
If you need further assistance feel free to contact Technical Support.
I found this workaround, should work until Apple/Mathworks issues a patch:
Download the Apple Java SE 2013-003 update (no longer on the Apple website but I found this link: http://apple-java-for-mac.en.softonic.com/mac/download)
Then download and install Pacifist http://www.charlessoft.com
Use Pacifist to open the Apple Java package and install using the install option of Pacifist.
Your Java SE should be downgraded to where it was prior to applying the 2013-004 patch. This worked for me, matlab is functional again.
As Art noticed first, a new update to Java was posted on Friday. Run Software Update, and if that does not correct the problem, you will need to download and install the update manually:

Thanks once again for your patience; we especially appreciate everyone chipping in here with suggestions and workarounds.

Another method for OS X 10.7/10.8:
Note that this may also remove any other versions of Java installed alongside 1.6
Download Java 2013-003 from http://apple-java-for-mac.en.softonic.com/mac/download
In Terminal, copy and paste these 3 commands to remove enough of the new Java version to allow re-installation of Java 1.6.0_45:
sudo rm -rf /System/Library/Java/JavaVirtualMachines sudo rm -rf /System/Library/Frameworks/JavaVM.framework sudo pkgutil --forget com.apple.pkg.JavaForMacOSX107
Then open the downloaded disk image and install JavaForOSX.pkg
You will now need to turn off automatic system updates, and refrain from installing the 2013-004 update when it gets offered again via the App Store.
Both MathWorks and Apple are aware of the problem, and we are actively investigating. We will post updates here as we learn more. As others have reported, MATLAB versions R2012b and earlier are impacted. The only identified work-around just now is to use Time Machine or similar means to revert to the previous Java release.
Thanks for your understanding and patience.

Here is the support roadmap:
On Mountain Lion (OS X 10.8) MATLAB R2012b is supported but not releases prior to that.
I found a temporary workaround for OS 10.6.8 at least, and involves no installations:
Close all programs
Go to Applications / Utilities / Java Preferences
The Java Prefs app will open
In the 'General' Tab, change the order of Java SE, so that the two with the older versions are on top. The versions are in the RH column on my system. For example, my toplisted version was 1.6.0_51..., which is the latest version updated yesterday. There were also two entries for 1.6.0_24... Drag these so they are on top (64-bit first)
Close the app
Start MATLAB. Now I can type and everything is good.
I ran into this problem today. If you have a time machine backup, you can simply replace /System/Library/Java with a time machine backup from before the update. No need to install anything. https://discussions.apple.com/message/22294042#22294042
it is inconceivable that the apple makes available an update without first being her some of its operation. is inconceivable block the work of the people.
Apple has released a new version of the 1.6.0_51 update, so it is no longer necessary to hack a downgrade. The fix is described here: http://lists.apple.com/archives/java-dev/2013/Jun/msg00055.html
You have to manually download the JavaForOSX2013-0004 update. I've tried it and it restored my Matlab to working again. This was a rather nasty mix-up.
So, how about Java 7 support on OS X sometime this century?
Why do I have to install EOL Java 6 just to install your stuff? Most developers simply fail to build for 64-bit, but you guys are 64-bit, and still not Java 7 compliant. What gives?
It's time to get JAVA itself on your Product Roadmap as well: http://www.mathworks.com/support/sysreq/roadmap.html ...which seems long overdue.
Shame the Java update was not rolled out as a 'Software Update', or if it was my Pro didn't do it. I've had heartache for a couple of months almost making me buy a new Pro and Matlab V13 :-) - Damm it now works...
