Proof step 15 from proof isobj-addarray-other (previous step)

is_obj(r, st) ⊦ r = r0, is_obj(r, addarray(r0, ty0, vals, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ 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 14:
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) ⊦ r = r0, is_obj(r, addarray(r0, ty0, vals, st))
