inFamix throws NullPointerException error at generate the MSE file for Java Project

Hi,

I put my java source code directory in the root folder of the infamix. At execute the command to generate MSE file, the infamix throws the NullPointerException while processing a class.

The MSE file is generated, but I dont know if this can to cause problems in the model.

What is the cause this problem?
