Proof step 5 from proof validref-bytearray (conclusion)

⊦ validref(str, r, mkarraytype(byte_type), st) ↔ r = jvmref ∨ okbytearray(r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ ¬ okbytearray(r, st) ∧ r ≠ jvmref → ¬ validref(str, r, mkarraytype(byte_type), st)
Proof step 2:
⊦ validref(str, jvmref, ty, st)
Proof step 4:
okbytearray(r, st) ⊦ r = jvmref, validref(str, r, mkarraytype(byte_type), st)

Rule argument
