Proof step 74 from proof validstatfield-putrkvs (previous step)

validvals(str, rkvs, st), mkfs(class, ty, fieldvar) ' ∈ statfields(class), tdname∃(str, class), initdone(class, st), validfield(str, jvmref, mkfs(class, ty, fieldvar) ', st) ⊦ validfield(str, jvmref, mkfs(class, ty, fieldvar) ', st[rkvs]), _uninit ∈ rkvs, jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ rkvs

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 8:
⊦ validfield(str, r, sk, st) ↔ goodfieldandtype(r, sk, st) ∧ type∃(str, sk .fs .type) ∧ sk .fs .type ≠ void_type ∧ (is_reftype(sk .fs .type) → validrefval(str, st[r -- sk], sk .fs .type, st))
Proof step 73:
validvals(str, rkvs, st), mkfs(class, ty, fieldvar) ' ∈ statfields(class), tdname∃(str, class), initdone(class, st), validfield(str, jvmref, mkfs(class, ty, fieldvar) ', st) ⊦ goodfieldandtype(jvmref, mkfs(class, ty, fieldvar) ', st[rkvs]) ∧ type∃(str, mkfs(class, ty, fieldvar) ' .fs .type) ∧ mkfs(class, ty, fieldvar) ' .fs .type ≠ void_type ∧ ( is_reftype(mkfs(class, ty, fieldvar) ' .fs .type) → validrefval(str, st[rkvs][jvmref -- mkfs(class, ty, fieldvar) '], mkfs(class, ty, fieldvar) ' .fs .type, st[rkvs])), _uninit ∈ rkvs, jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ rkvs
