(was: The current snapshot build 
([https://repository.apache.org/content/groups/snapshots/org/apache/activemq/apache-artemis/2.11.0-SNAPSHOT/apache-artemis-2.11.0-20200107.031417-52-bin.zip)]
 is running again under Windows 10, therefore I checked the behavior of the 
original issue using this snapshot. Unfortunately, the behavior has not 
changed: questions posted in my comments still pertain.)

> Message permanently in "delivering" state if a JMS XA client crashes

>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: Broker, Web Console
>    Affects Versions: 2.10.1
>         Environment: Windows 10
>            Reporter: miroch
>            Priority: Critical
>         Attachments: ArtemisXaReceiveCrashTest.java, ArtemisXaSender.java,

> h2. Symptoms:
> If a message is created and sent to a queue using the *ArtemisMQ Web console* 
> and then read by the JMS XA client program, but the client crashes before it 
> completes its XA transaction, the ArtemisMQ server correctly recognizes that 
> the client has died. However, the message does not "return" to the queue. 
> Instead, it remains "delivering" permanently and thus it is not accessible 
> anymore (until ArtemisMQ server is restarted: the things normalize 
> afterwards).
> h2. Steps to reproduce:
> 1. Note that due to a nature of this bug it is not possible to demonstrate it 
> in an embedded environment. A separate instance of Artemis MQ is needed 
> instead. Therefore install the ArtemisMQ 2.10.1 
> (https://www.apache.org/dyn/closer.cgi?filename=activemq/activemq-artemis/2.10.1/apache-artemis-2.10.1-bin.zip&action=download)
>  and use its out-of-the-box configuration with only a single change: add the 
> address for exampleQueue into broker.xml, so that the queue is permanently 
> visible in the WebConsole:
> {{<address name="exampleQueue">}}
> {{    <anycast>}}
> {{        <queue name="exampleQueue" />}}
> {{    </anycast>}}
> {{</address>}}
> 2. Access the WebConsole and navigate to exampleQueue. Then send a durable 
> plain text message *via WebConsole (this is important)* into this queue.
> 3. Setup the XA client. The attached source-code is based on the example 
> "xa-recieve" from 
> https://github.com/apache/activemq-artemis/tree/master/examples/features/standard/xa-receive
> The client code is located in ArtemisXaReceiveCrashTest. In order to get it 
> running, add DummyXid and jndi.properties from 
> https://github.com/apache/activemq-artemis/blob/master/examples/features/standard/xa-receive/src/main/java/org/apache/activemq/artemis/jms/example/DummyXid.java
>  and 
> https://github.com/apache/activemq-artemis/blob/master/examples/features/standard/xa-receive/src/main/resources/jndi.properties,
>  respectively. The only library needed is artemis-jms-client-all (version 
> 2.10.1): see the attached pom.xml
> 4. Run the main method of ArtemisXaReceiveCrashTest. It reads the message out 
> of exampleQueue within an XA-transaction, however, it terminates the Java VM 
> before rolling-back or committing the transaction.
> 5. If you now execute the method "browse()" for the queue exampleQueue via 
> WebConsole, it returns an empty list. If you execute the method 
> listDeliveringMessages() for the queue exampleQueue via WebConsole, it 
> returns an empty list. If you execute the method countDeliveringMessages() 
> for the queue exampleQueue via WebConsole, it returns 1. This state is 
> permanent: the message does not reappear back in the queue. The situation 
> normalizes after the ArtemisMQ server is restarted: the message is then again 
> available for delivery.
> h2. Variations:
>  * The situation does not improve, if the JMS XA client closes the connection 
> and session properly and terminates without rolling-back or committing the 
> transaction. The behaviour is the same. This can be simulated, if the line 
> containing "System.exit(0)" in ArtemisXaReceiveCrashTest is commented out.
>  * On the other hand, if the message is created and sent programmatically 
> using the attached program ArtemisXaSender (again based on an ArtemisMQ 
> example "xa-receive") instead of the WebConsole, the server behaviour is 
> correct: after the reading XA client crashes, the message correctly appears 
> back in the exampleQueue. Therefore it seems that the problem is somehow 
> related to the way the WebConsole sends and/or formats the message.
>  * If the reading client is transacted, but no XA-client, there is no 
> problem, even if the message is sent via WebConsole.
