Proof step 17 from proof putbar-classfield-onlymod (previous step)

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

And obtained the following new goals

Proof step 16:
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), validrefs(str, r1 ', ty, st)
