Hi Michael thanks a lot for your hints,
below test which expose the problem. It seems as follows: after
deserialization entity state is null. Maybe this is acceptable behavior -
meaning entities are not supposed to be serializable, or it is an issue
which should be fixed?
I added this test case to WorldRepositoryTest in
spring-data-neo4j-hello-worlds-aspects project:
@Test
public void testSerialization() throws Exception {
World myWorld = new World( "mine", 0 ).persist();
EntityState<Node> entityState = myWorld.getEntityState();
assertNotNull(entityState);
Iterable<World> foundWorlds = galaxy.findAll();
World mine = foundWorlds.iterator().next();
byte[] serializedWorld = SerializationUtils.serialize(mine);
World deserializedWorld = (World)
SerializationUtils.deserialize(serializedWorld);
assertNotNull(deserializedWorld);
EntityState<Node> deserializedEntityState =
deserializedWorld.getEntityState();
assertNotNull(deserializedEntityState); //Test fails at this
assertion
template.save(deserializedWorld);//This invocation leads to NPE
since entityState is null
assertEquals(myWorld.getName(),deserializedWorld.getName());
}
Running similar operation in project with no aspectj doesn't lead to this
problem.
Thanks a lot for your feedback.
