Proof step 10 from proof validrefnotnull-getarray-subset (conclusion)

⊦ validrefnotnull(str, r, mkarraytype(ty), st) ∧ 0 ≤ i ∧ i + j ≤ st[r -- _length] .intval ∧ st ⊆ st1 → getarray(r, i, j, st) = getarray(r, i, j, st1)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ validrefnotnull(str, r, ty, st) → r ≠ jvmref
Proof step 9:
validrefnotnull(str, r, mkarraytype(ty), st), i + j ≤ st[r -- _length] .intval, st ⊆ st1, 0 ≤ i ⊦ getarray(r, i, j, st) = getarray(r, i, j, st1), r = jvmref
