Proof step 19 from proof predef-supers-rec (conclusion)

⊦ class ≠ `java.lang.Object' .class ∧ is_predefined_class(class) → predef_supers(class) = class ' + predef_supers(predef_superClass(class))

And obtained the following new goals

Proof step 1:
⊦ is_predefined_class(class) ∧ class ≠ `java.lang.Object' .class → predef_superClass(class) = predef_supers(class) .rest .first
Proof step 18:
is_predefined_class(class) ⊦ class = `java.lang.Object' .class, predef_supers(class) = class ' + predef_supers(predef_supers(class) .rest .first)
