Switching the java version in MATLAB on OS X 10.8

Question

I have already set my MATLAB_JAVA variable as explained here and my system says java version 1.7.0_25 when I type java -version however, when I go to MATLAB and type version -java it says Java 1.6.0_51-b11-457-11M4509 with Apple Inc. Java HotSpot(TM) 64-Bit Server VM mixed mode . How do I get it so that it sees Java 1.7 in Mountain Lion 10.8?

Answer 1

This problem is fixed with newer releases of Matlab. R2013a, which it looks like you were running, was stuck with the Apple-distributed 1.6 JVM on OS X. Starting with R2013b, Matlab on OS X ships with a bundled JVM like it does on other platforms, and MATLAB_JAVA works now. And the bundled JVM is 1.7. So this issue can be fixed by upgrading to R2013b or later.
