User applied rule exists right

And obtained the following new goals

Proof step 19:
st[r -- fs '] = refval(r1), st[r -- _type] .type = mkclasstype(class), is_obj(str, r, st), fs ' ∈ instfields(class), okbytearray(r1, st) ⊦ r = jvmref, r = r1, st[r1 -- sk0] = (putByteArray(bytes, r1, st)[r1 -- sk0]), junkref(str, r, st), fs ' ∈ instfields(class) ∧ is_referencevalue(st[r -- fs ']) ∧ r1 = st[r -- fs '] .refval ∧ validrefs(str, st[r -- fs '] .refval ', fs .type, st)
