Proof step 27 from proof validrefnotnull-putbar (previous step)

∀ r0, st, str, r, ty, i. okbytearray(r0, st) ∧ validrefnotnull(str, r, ty, st) → r = r0 ∨ r = jvmref ∨ validrefnotnull(str, r, ty, putByteArray(bytes0, r0, i, st)), okbytearray(r0, st), validrefnotnull(str, r, ty, st) ⊦ r = r0, r = jvmref, validrefnotnull(str, r, ty, putByteArray(by + bytes0, r0, i, st))
