Proof step 14 from proof validref-put-01 (previous step)

User applied rule insert rewrite lemma

And obtained the following new goals

• Proof step 3:

  ⊦ is_obj(r, st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_classtype(st[r -- _type] .type) ∧ is_obj(r, st[r -- _type] .type .class, st)

• Proof step 13:

  ⊦ r = r0, r0 ≠ jvmref ∧ r0 -- _type ∈ st[r -- sk, val] ∧ is_typevalue(st[r -- sk, val][r0 -- _type]) ∧ is_classtype((st[r -- sk, val][r0 -- _type]) .type) ∧ is_obj(r0, (st[r -- sk, val][r0 -- _type]) .type .class, st[r -- sk, val]) ∨ is_array(r0, st[r -- sk, val]) ↔ is_obj(r0, st) ∨ is_array(r0, st)
