Hi, when I try to start a matlabpool in R2102B I receive the following error
>> 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)
Similarly if try to do in R2013A I received the following error
>> 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)
Can you please advise how to fix this problem.
Thank you, Glenn

This fix worked for me on a MacBook Pro Retina with Matlab2012b.
Just be careful not to delete all files in the respective folders when you copy them over to the Matlab.app folder
