MATLAB: Can I run MATLAB 7.11 (R2010b) with JVM 1.5 (older version) by using the MATLAB_JAVA environment variable

Question

I would like to run my MATLAB 7.11 (R2010b) using JVM 1.5 by setting the MATLAB_JAVA environment variable. MATLAB 7.11 (R2010b) normally ships with the newer JVM 1.6. Is this switch possible?

Answer 1

This is not possible and MATLAB will fail to start unless the '-nojvm' option is specified.

Although it is recommended not to change the MATLAB JVM, setting the MATLAB_JAVA environment variable to later JVM versions than the MATLAB shipped version should still work.
