https://github.com/apache/activemq-artemis/pull/1676
The failover is blocking because client applications would fail and would
require to block.. it's customer's code.
I reckon we could do asynchronously for MDBs or message listeners. so, how
do you differentiate the two here?
I suspect Failover (FailoverTest and others on the testsuite) wouldn't work.
Also.. at least you should make this change on master.. it's a significant
refactoring to make something like this to work properly. Failover itself was a
pain.. making this level.. even more difficult.

> Key: ARTEMIS-1527

> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 1.5.5
> Reporter: Jiri Ondrusek
>
> {code}
> java.lang.AssertionError: null
> at org.junit.Assert.fail(Assert.java:86)
> at org.junit.Assert.assertTrue(Assert.java:41)

> {code}
> Maximum size of clients global thread pool is computed as {{8 *
> Runtime.getRuntime().availableProcessors()}}. In the case of CPU with one
> core, the thread pool has maximum size 8.
> The test fails because of following situation. When the server is stopped,
> all ClientSessionFactoryImpl try to reconnect and they add executor to the
> thread pool which tries to reconnect ad anfinitum, see \[1\]. These threads
> employ the whole thread pool and the rest is not able to work in normal way.
> For example, I can see warnings \[2\].
> This situation is known as Starvation or Livelock \[3\]. I think that the
> system should work properly even if the maximum size of thread pool will be 2.
> *Steps to reproduce:*
> Modify the test in the following way:
> {code}
> @Test
> public void testServerShutdownAndReconnect() throws Exception {
> ActiveMQClient.clearThreadPools();
> ActiveMQClient.setGlobalThreadPoolProperties(2, 1);
> ActiveMQResourceAdapter qResourceAdapter = newResourceAdapter();
> ...
