Proof step 27 from proof superClass-predef (conclusion)

⊦ is_predefined_class(predef_superClass(class))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ is_predefined_class(class) → predef_superClass(class) = `java.lang.Object' .class
Proof step 25:
¬ ¬ is_predefined_class(class) ⊦ is_predefined_class(predef_superClass(class))
Proof step 26:
⊦ is_predefined_class(`java.lang.Object' .class)
