问题
Problem: GUIDE guis are missing their usual features (drop-down, push-buttons, etc). They just appear as empty windows with borders delineating where the different buttons used to be. The issue appears to be related to the jre version I am using. I don't know how to proceed.
Here's the environment variables matlab is using. /usr/java/default points to the root directory of jre_1.7.0_05 contain bin, lib etc.
------------------------------------------------------------------------
-> (.matlab7rc.sh) sourced from directory (DIR = $MATLAB/bin)
-> DIR = /opt/matlab/R2011b/bin
------------------------------------------------------------------------
a = argument e = environment r = rcfile s = script

-> r MATLAB = /opt/matlab/R2011b
-> LM_LICENSE_FILE = (variable not defined)
-> MLM_LICENSE_FILE = (variable not defined)

回答1:
Bottom line is a lot of things in MATLAB break with Java 7, revert back to latest Java 6 (you can have both installed at the same time).
Just set $MATLAB_JAVA environment variable to point to a JRE6 installation.
