Pavel Tupitsyn updated IGNITE-1863:
------------------------------------
Description:
IgniteAtomicReference allows null as a value, but when current value is null,
compareAndSet does not work:
{code}
IgniteAtomicReference<String> atomic =
ignite.atomicReference(atomicName, null, true);
assertEquals(null, atomic.get());
boolean res = atomic.compareAndSet(null, "x");
assertTrue(res); // fail
assertEquals("x", atomic.get()); // fail
{code}
