  Matlab actors also have 32 and 64 bit issue when using JNI libraries to
communicate with Matlab. It will pop up an exception message when the JNI lib
doesn't work with the system. You can find some information at
https://kepler-project.org/developers/teams/build/matlab-lib-build-instructions-in-kepler-for-matlab-actor.
It may help this bug.
