Dave Syer updated AMQ-2233:
---------------------------
Attachment: RawRollbackSharedConsumerTests.java
Added shared consumer test case. This passes in 5.3-SNAPSHOT even without the
fetch size hint as predicted. But it also fails in 5.2.0, which still seems
like a bug to me, considering what you said above. What do you think?
> After rollback received messages not re-presented

> Key: AMQ-2233
> URL: https://issues.apache.org/activemq/browse/AMQ-2233
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.2.0
> Reporter: Dave Syer
> Assignee: Gary Tully
> Attachments: RawRollbackSharedConsumerTests.java,
> RawRollbackTests.java
>
>
> After rollback received messages not re-presented. If I receive in a
> transaction and then roll back the messages should be re-presented in the
> next transaction. This used to work in 5.1.0, but is broken in 5.2.0.
> You can browse the Queue in JMX after the rollback and see that the messages
> are still there, but they are not received by a consumer in the same process.
> Here's a test case (fails on the checkPostConditions()):
> {code}
> public class RawRollbackTests {
>
> private static ConnectionFactory connectionFactory;
> private static Destination queue;
> private static BrokerService broker;
> @BeforeClass
> public static void clean() throws Exception {
> FileUtils.deleteDirectory(new File("activemq-data"));
> broker = new BrokerService();
> broker.setUseJmx(true);
> broker.start();
> ActiveMQConnectionFactory connectionFactory = new
> ActiveMQConnectionFactory();
> connectionFactory.setBrokerURL("vm://localhost?async=false");
> RawRollbackTests.connectionFactory = connectionFactory;
> queue = new ActiveMQQueue("queue");
> }
> @AfterClass
> public static void close() throws Exception {
> broker.stop();
> }
> @Before
> public void clearData() throws Exception {
> getMessages(false); // drain queue
> convertAndSend("foo");
> convertAndSend("bar");
> }
> @After
> public void checkPostConditions() throws Exception {
> Thread.sleep(1000L);
> List<String> list = getMessages(false);
> assertEquals(2, list.size());
