Fixed slow MATLAB UI response on mountain lion

The slow UI is due to a recent Apple Java update (build 1.6.0_51-b11-456-10M4508), which impacts <= 2012b and made me feel awful. To check, just type command in MATLAB console:

version -java

If you get 1.6.0_51-b11-456-10M4508, you may encounter this problem.

Apple has fixed in another patch, and just installing this patch manually fixes the issue finally. Here is the link:

After installing, check again with version -java, you should get the msg like:

Java 1.6.0_51-b11-457-11M4509
