Proof step 6 from proof isarray-bytearray (previous step)

st[r -- _type] .type = mkarraytype(byte_type), is_array(r, st) ⊦ r = jvmref, okbytearray(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 5:
st[r -- _type] .type = mkarraytype(byte_type), is_array(r, st) ⊦ r = jvmref, okarray(r, byte_type, st)

Rule argument

[crewrite-arg: okbytearray-01, F, [st, r] → [st, r]]
