Proof step 25 from proof validstatfield-throw-predef (previous step)

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

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 24:
sk = fs ', validstatfield(str, sk, st), is_predefined_class(class), newref(r, st), is_fskey(sk) ⊦ r = jvmref, (initdone(fs .class, st) → validfield(str, jvmref, sk, addobj(r, class, [], st)[_mode, throw(r, mkclasstype(class))])) ∧ tdname∃(str, fs .class) ∧ sk ∈ statfields(fs .class)
