      I'm developing a program that does incremental compilation.
       
      I have a Models file containing a "declare". Filename "Drools-0.drl".
       
      And I have a file with some rules. Name "Rule-1221.drl".
       
      I created another file called "Rule-1221-2.drl". With a single change.
       
      The Model was never updated. But it gives "cannot cast"

      java.lang.ClassCastException: class myPkg.StringWrapper cannot be cast to class myPkg.StringWrapper (myPkg.StringWrapper is in unnamed module of loader org.drools.dynamic.DynamicProjectClassLoader$DefaultInternalTypesClassLoader @30b34287; myPkg.StringWrapper is in unnamed module of loader org.drools.dynamic.DynamicProjectClassLoader$DefaultInternalTypesClassLoader @309028af)
