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

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 ...

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.
