EXCEPTION_ACCESS_VIOLATION help (jLabel and MATLAB deployed JAR file)

Hi my program needs to perform two actions subsequently: 1) read text from a jlabel 2) instantiate a class from a jar file. The jar file was built and packaged from matlab R2008B.

It runs fine when ONE of the two actions are performed, but for some reason crashes as soon as BOTH are performed.

I'd appreciate any help or advice as to where I should begin to start solving this problem.

Error Message that I get:
