Proof step 4 from proof okbar-nopath (previous step)

okbytearray(r, st), validrefs(str, r ' + refs0, mkclasstype(`java.lang.Object' .class), st) ⊦ r = (r ' + refs0) .last, is_array(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)

Rule argument

[speclemmaarg: ,okbytearray(r, st) ↔ okarray(r, byte_type, st) ,[st, r] → [st, r] ,F ,okfuns , ,okbytearray-01 ]
