Proof step 27 from proof validstatfield-throw-predef (previous step)

validstatfield(str, sk, st), is_predefined_class(class), newref(r, st) ⊦ r = jvmref, validstatfield(str, sk, addobj(r, class, [], st)[_mode, throw(r, mkclasstype(class))])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validstatfield(str, sk, st) ↔ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st))
Proof step 26:
validstatfield(str, sk, st), is_predefined_class(class), newref(r, st) ⊦ r = jvmref, is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ ( initdone(sk .fs .class, addobj(r, class, [], st)[_mode, throw(r, mkclasstype(class))]) → validfield(str, jvmref, sk, addobj(r, class, [], st)[_mode, throw(r, mkclasstype(class))]))

Rule argument
