Proof step 4 from proof validref-throw (previous step)

validref(str, r0, ty, st), newref(r, st) ⊦ r = jvmref, validref(str, r0, ty, addobj(r, class, [], st)[_mode, throw(r, mkclasstype(class))])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ rk1 .ref = jvmref ∧ r ≠ jvmref → (validref(str, r, ty1, st[rk1, val]) ↔ validref(str, r, ty1, st))
Proof step 2:
⊦ validref(str, jvmref, ty, st)
Proof step 3:
⊦ newref(r1, st) ∧ validref(str, r, ty1, st) → validref(str, r, ty1, addobj(r1, class, fis, st))

Rule argument

[crewrite-arg: validref-put-statfield , F , [val, rk1, st, ty1, r, str] → [throw(r, mkclasstype(class)), _mode, addobj(r, class, [], st), ty, r0, str] ]
