MATLAB: Is it possible to use the MATLAB Java interface to load a MATLAB Builder JA generated JAR package

addassemblydeploydeploymentloadlibraryMATLABMATLAB Compiler SDK

I have created a Java JAR package by using the Java Package target of MATLAB Builder JA using the DEPLOYTOOL or MCC functions. I would like to load this package into the MATLAB workspace and call its functions.
I can add this JAR file to the dynamic path with JAVAADDPATH, but when I try to instantiate a class object from the package, I get the following exception:
 Java exception occurred:
 ... Matlab M-code Stack Trace ...
 com.mathworks.toolbox.javabuilder.MWException: Component created using MATLAB Builder JA cannot be
 loaded in MATLAB

This change has been incorporated into the documentation in Release 2012b (R2012b). For previous releases, read below for any additional information:
As seen in the error message, a JAR package generated by MATLAB Builder JA indeed cannot be loaded in MATLAB using the Java interface. There are no workarounds.
