Proof step 29 from proof nopathex-badarrayfield (previous step)

fs ' = _length, validrefs(str, r ' + refs0, st[r -- _type] .type, st), is_arraytype(st[refs0 .last -- _type] .type), contains(str, st[r -- _type] .type, st[refs0 .last -- _type] .type) ⊦ r = refs0 .last, refs0 = [], refs0 .last = jvmref, contains(str, st[r -- _type] .type, fs)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
⊦ r ≠ jvmref ∧ (¬ is_valid_ref(str, r, st) ∨ ¬ st[r -- _type] .type ≤ ty) → ¬ validrefs(str, r ' + refs, ty, st)
Proof step 28:
¬ (r ≠ jvmref ∧ (¬ is_valid_ref(str, r, st) ∨ ¬ st[r -- _type] .type ≤ st[r -- _type] .type)), fs ' = _length, validrefs(str, r ' + refs0, st[r -- _type] .type, st), is_arraytype(st[refs0 .last -- _type] .type), contains(str, st[r -- _type] .type, st[refs0 .last -- _type] .type) ⊦ r = refs0 .last, refs0 = [], refs0 .last = jvmref, contains(str, st[r -- _type] .type, fs)
