Proof step 34 from proof junkref-put-refval-01 (conclusion)

⊦ ¬ junkref(str, r, st) ∧ validref(str, r1, ty, st) ∧ mkarraytype(ty) ≤ st[r0 -- _type] .type ∧ r0 ≠ jvmref ∧ is_arraytype(st[r0 -- _type] .type) ∧ (r1 = jvmref → is_reftype(ty)) → ¬ junkref(str, r, st[r0 -- i ', refval(r1)])

And obtained the following new goals

Proof step 33:
is_arraytype(st[r0 -- _type] .type), mkarraytype(ty) ≤ st[r0 -- _type] .type, validref(str, r1, ty, st), junkref(str, r, st[r0 -- i ', refval(r1)]), r1 = jvmref → is_reftype(ty) ⊦ r0 = jvmref, junkref(str, r, st)
