Proof step 115 from proof compat-addclass (previous step)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 96:
⊦ is_predefined_class(class) → statfields(class) = []
Proof step 114:
is_predefined_class(`java.lang.Object' .class), sk .fs = mkfs(class, ty, fieldvar), fis .keys = [], sk ∈ statfields(class0), tdname∃(str, class0), initdone(class0, addclass(`java.lang.Object' .class, fis, st)), okfieldinits(`java.lang.Object' .class, fis), compatrefs(str, st), compatmode(str, st) ⊦ `java.lang.Object' .class = class0, initdone(class0, st), jvmref -- sk ∈ addclass(`java.lang.Object' .class, fis, st) ∧ ¬ is_indexkey(sk) ∧ compat(str, addclass(`java.lang.Object' .class, fis, st)[jvmref -- sk], ty, addclass(`java.lang.Object' .class, fis, st))
