Proof step 9 from proof validstatfield-throw-predef (previous step)

type∃(str, ty), is_reftype(ty), is_predefined_class(class), newref(r, st), mkfs(class0, ty, fieldvar) ' ∈ statfields(class0), tdname∃(str, class0), initdone(class0, st), jvmref -- mkfs(class0, ty, fieldvar) ' ∈ st, is_referencevalue(st[jvmref -- mkfs(class0, ty, fieldvar) ']), validrefval(str, st[jvmref -- mkfs(class0, ty, fieldvar) '], ty, st), jvmref ∈ st ⊦ r = jvmref, ty = void_type, validrefval(str, st[jvmref -- mkfs(class0, ty, fieldvar) '], ty, addobj(r, class, [], st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 8:
⊦ validrefval(str, val, ty, st) ∧ newref(r, st) → validrefval(str, val, ty, addobj(r, class, fis, st))

Rule argument

[crewrite-arg: validrefval-addobj , F , [st, fis, class, r, ty, val, str] → [st, [], class, r, ty, st[jvmref -- mkfs(class0, ty, fieldvar) '], str] ]
