Proof step 32 from proof okbytearray-validref (previous step)

okarray(r, byte_type, st) ⊦ r = jvmref, r = jvmref ∨ st[r -- _type] .type ≤ mkarraytype(byte_type) ∧ ¬ junkref(str, r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 31:
okarray(r, byte_type, st), junkref(str, r, st), r ∈ st ⊦ r = jvmref

Rule argument
