Proof step 4 from proof junkref-voidarray (previous step)

¬ (r ≠ jvmref ∧ ¬ is_valid_ref(str, r, st)), st[r -- _type] .type = mkarraytype(void_type) ⊦ r = jvmref, junkref(str, r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
st[r -- _type] .type = mkarraytype(void_type), is_array(str, r, st) ⊦ r = jvmref, junkref(str, r, st)

Rule argument
