Proof step 24 from proof validrefkeynotnull-put-shortval (previous step)

sk = fs ', fs .type = short_type, is_shortvalue(st[r -- sk]), validrefkeynotnull(str, rk, ty, st), is_fskey(sk) ⊦ sk = _length, r = jvmref, validrefkeynotnull(str, rk, ty, st[r -- sk, shortval(sho)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 23:
fs .type = short_type, is_shortvalue(st[r -- fs ']), validrefkeynotnull(str, rk, ty, st) ⊦ fs ' = _length, r = jvmref, validrefkeynotnull(str, rk, ty, st[r -- fs ', shortval(sho)])
