I'm triggering code completion in a class that extends from an unresvoled type. As the superclass is not imported in my scenario wala returns null for the superclass. This state is not allowed in wala as my class is not Object. java.lang.IllegalStateException: No superclass found for <Application,Ldata/CompletionOnNonPublicMembersOfSuperClassInMethod> Superclass name LFieldsWithDifferentVisibilities at com.ibm.wala.classLoader.BytecodeClass.getSuperclass(BytecodeClass.java:237) at

What can we do to get around this exception? Is there any solution we can do or does the chain completion have to take care of this?
I tend to believe that this is obsolete now with the latest changes. Closing.
