Proof step 15 from proof putbar-classfield-onlymod (previous step)

st[r -- _type] .type = mkclasstype(class), st[r -- mkfs(class0, ty, fieldvar) '] = refval(r1), okbytearray(r1, st), mkfs(class0, ty, fieldvar) ' ∈ instfields(class), is_obj(str, r, st) ⊦ st[r1 -- sk0] = (putByteArray(bytes, r1, st)[r1 -- sk0]), r = r1, r = jvmref, junkref(str, r, st), r1 = jvmref ∨ r1 ≠ jvmref ∧ is_valid_ref(str, r1, st) ∧ st[r1 -- _type] .type ≤ ty

Proof step 14:
st[r -- _type] .type = mkclasstype(class), st[r -- mkfs(class0, ty, fieldvar) '] = refval(r1), okbytearray(r1, st), mkfs(class0, ty, fieldvar) ' ∈ instfields(class), is_obj(str, r, st) ⊦ st[r1 -- sk0] = (putByteArray(bytes, r1, st)[r1 -- sk0]), r = r1, r = jvmref, r1 = jvmref, junkref(str, r, st), mkarraytype(byte_type) ≤ ty
