Another case,
KEM kem = KEM.getInstance("DHKEM");
   KEM.Encapsulator e1 = kem.newEncapsulator(pk, random);
KEM kem1 = KEM.getInstance("DHKEM");
   KEM.Encapsulator e2 = kem1.newEncapsulator(pk, random);
byte[] enc1 = e1.encapsulate().encapsulation();
byte[] enc2 = e2.encapsulate().encapsulation();
Asserts.assertFalse(Arrays.equals(enc1, enc2));

Can this case be added too?
