How to fix the matlabpool problem in Matlab for MAC OS X?

I run a toolbox including matlabpool on MAC using MATLAB 2012b + Xcode 4.6.3 + Java 7 update 65, but it reported the following errors:

-------------------------

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)

Error in openPool (line 13) matlabpool;

------------------------

Though a possible resolution can be found at http://www.mathworks.com/support/bugreports/919688, it seems does not work. Open "Parallel" -> "Manage Cluster Profiles", and it reported the following errors:

------------------------

Attempt to reference field of non-structure array.

Error in parallel.internal.ui.ValidationManager (line 31) obj.Validator.addlistener('ValidationStarted', ...

------------------------

How can I avoid these errors?

Any comments are appreciated. Thanks.
