Invalid LOC Header zipexception

Actually I'm having an issue i can't explain. I'm getting the next exception in a test which should go through al classes inside a concrete package and test one modeal function which everyone of them has to implement.

 @Test
  public void testConcreteModels()
      throws IOException, InstantiationException, IllegalAccessException, NotFoundException, CannotCompileException {
    // Loop through classes in the model package
    final ClassLoader loader = Thread.currentThread().getContextClassLoader();
    for (final ClassPath.ClassInfo info : ClassPath.from(loader).getTopLevelClassesRecursive(MODEL_PACKAGE)) {

And the excepcion is next....
