Proof step 48 from proof disjoint-forward-array (conclusion)

⊦ r ∈ refs ∧ r1 ∈ refs ∧ r ≠ r1 ∧ ¬ junkref(str, r1, st) ∧ ¬ disjoint(str, (refs -l r1) + st[r1 -- i '] .refval, st) ∧ 0 ≤ i ∧ i < st[r1 -- _length] .intval ∧ r1 ≠ jvmref ∧ is_arraytype(st[r1 -- _type] .type) → ¬ disjoint(str, refs, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 47:
disjoint(str, refs, st), r ∈ refs, r1 ∈ refs, i < st[r1 -- _length] .intval, is_arraytype(st[r1 -- _type] .type), 0 ≤ i, 0 < st[r1 -- _length] .intval ⊦ r1 = jvmref, r = r1, junkref(str, r1, st), disjoint(str, (refs -l r1) + st[r1 -- i '] .refval ', st)
