Proof step 15 from proof validrefkeynotnull-put-shortval (previous step)

is_referencevalue(st[rk]) ∧ validrefnotnull(str, st[rk] .refval, 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)])

And obtained the following new goals

Proof step 6:
⊦ validrefnotnull(str, r, ty, st) → r ≠ jvmref
Proof step 14:
is_referencevalue(st[rk]), validrefnotnull(str, st[rk] .refval, ty, st), rk ∈ st, is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']) ⊦ r = jvmref, st[rk] .refval = 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)])
