Proof step 5 from proof junkref-okarray-byte (previous step)

okarray(refval(r), byte_type, st[r -- _length] .intval, st), junkref(str, r, st) ⊦ r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ okbytearray(r, st) → ¬ junkref(str, r, st)
Proof step 4:
¬ okbytearray(r, st), okarray(refval(r), byte_type, st[r -- _length] .intval, st), junkref(str, r, st) ⊦ r = jvmref

Rule argument

[crewrite-arg: bytearray-is-no-junk, F, [st, r, str] → [st, r, str]]
