And obtained the following new goals

Proof step 25:
⊦ fits(jvmref, sks, st) ↔ sks = []
Proof step 26:
st[r -- _type] .type = mkarraytype(ty), st[r -- i '] = refval(r1), is_array(str, r, st), r ∈ st, r -- i ' ∈ st, fits(r1, sks0, st), i < st[r -- _length] .intval, 0 < st[r -- _length] .intval, 0 ≤ i, st[r1 -- _type] .type ≤ ty, ∀ str0, r0, st0. ¬ junkref(str0, r0, st0) ∧ fits(r0, sks0, st0) → r0 -- sks0 ∈ st0 ⊦ r = jvmref, sks0 = [], r1 = jvmref, r1 -- sks0 ∈ st, junkref(str, r1, st)
