Issues with MATLAB on OSX after Java Updates
Mac OSX 10.6.x - Feb 2013
The latest update to OSX 10.6 (Update 12) updates Java to a new version that has an issue known to cause problems with 'matlabpool' on the local configuration especially with R2011b and older. Please upgrade the OS to 10.7 or use a newer version of Matlab (R2012a or newer) which have workarounds for the same.
Description: Parallel Computing Toolbox code fails with Java Virtual Machine update 1.6.0_39. Running any Parallel Computing Toolbox code using a Java Virtual Machine (JVM) version of 1.6.0_39 or later might cause a NullPointerException to be thrown by the JVM. For example:
>> matlabpool open Error using matlabpool (line 134) Java exception occurred: java.lang.NullPointerException at java.util.logging.Logger.demandLogger(Logger.java:286) at java.util.logging.Logger.getLogger(Logger.java:321)
