Proof step 17 from proof validrefkeynotnull-put-shortval (previous step)

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

And obtained the following new goals

Proof step 4:
⊦ validrefvalnotnull(str, val, ty, st) ↔ is_referencevalue(val) ∧ validrefnotnull(str, val .refval, ty, st)
Proof step 16:
validrefvalnotnull(str, st[rk], ty, st), rk ∈ st, is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']) ⊦ r = jvmref, is_referencevalue(st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][rk]) ∧ validrefnotnull (str, (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][rk]) .refval, ty, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)])

Rule argument
