Proof step 6 from proof validrefs-bytearray-01 (previous step)

refs = r + refs0 ∧ refs ≠ [] ⊦ validrefs(str, refs, mkarraytype(byte_type), st) ↔ refs = [] ∨ refs = jvmref ' ∨ okbytearray(r, st) ∧ refs0 = []

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ validrefs(str, r ' + refs, mkarraytype(byte_type), st) ↔ refs = [] ∧ (r = jvmref ∨ okbytearray(r, st))
Proof step 5:
jvmref = r ∧ refs0 = [] ∨ okbytearray(r, st) ∧ refs0 = [] ⊦ validrefs(str, r ' + refs0, mkarraytype(byte_type), st)
