Richard Eckart de Castilho commented on UIMA-5554:
--------------------------------------------------
I am currently using this option
{noformat}
Class.forName("myJCasClassName", false, this.getClass().getClassLoader())
{noformat}
It just seems a bit strange that a normal `Class.forName()` call fails with
such an error. I didn't even try to do anything with the sofa although the
error message says "A JCas class field "sofa" is being initialized...".
Shouldn't the sofa be only set when I actually create an instance of the class,
i.e. in the constructor?
