Proof step 19 from proof validrefkeynotnull-put-shortval (previous step)

is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), validrefkeynotnull(str, rk, ty, st) ⊦ r = jvmref, validrefvalnotnull (str, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][rk], ty, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ validrefkeynotnull(str, rk, ty, st) ↔ rk ∈ st ∧ validrefvalnotnull(str, st[rk], ty, st)
Proof step 18:
is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), rk ∈ st ∧ validrefvalnotnull(str, st[rk], ty, st) ⊦ r = jvmref, validrefvalnotnull (str, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][rk], ty, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)])

Rule argument
