How to reproduce:
1) Dwonload
[https://raw.githubusercontent.com/apache/activemq-artemis/master/examples/features/clustered/clustered-static-oneway/src/main/resources/activemq/server0/broker.xml]
to /tmp/broker1.xml
2) Change block:
{code:java}
<connectors>
<connector name="netty-connector">tcp://localhost:61616</connector>
<!-- connector to the server1 -->
<connector name="server1-connector">tcp://localhost:61617</connector>
</connectors>
<!-- Acceptors -->
<acceptors>
<acceptor name="netty-acceptor">tcp://localhost:61616</acceptor>
</acceptors>
{code}
to
{code:java}
<connectors>
<connector name="netty-connector">tcp://172.17.0.1:61616</connector>
<!-- connector to the server1 -->
<connector name="server1-connector">tcp://172.17.0.1:61617</connector>
</connectors>
<!-- Acceptors -->
<acceptors>
<acceptor name="netty-acceptor">tcp://0.0.0.0:61616</acceptor>
</acceptors>
{code}
3) Download
[https://raw.githubusercontent.com/apache/activemq-artemis/master/examples/features/clustered/clustered-static-oneway/src/main/resources/activemq/server1/broker.xml]
to /tmp/broker2.xml
4) Replace block:
{code:java}
<!-- Connectors -->
<connectors>
<connector name="netty-connector">tcp://localhost:61617</connector>
<!-- connector to the server0 -->
<connector name="server2-connector">tcp://localhost:61618</connector>
</connectors>
<!-- Acceptors -->
<acceptors>
<acceptor name="netty-acceptor">tcp://localhost:61617</acceptor>
</acceptors>
{code}
with:
{code:java}
<!-- Connectors -->
<connectors>
<connector name="netty-connector">tcp://172.17.0.1:61617</connector>
<!-- connector to the server0 -->
<connector name="server2-connector">tcp://172.17.0.1:61618</connector>
</connectors>
<!-- Acceptors -->
<acceptors>
<acceptor name="netty-acceptor">tcp://0.0.0.0:61617</acceptor>
</acceptors>
{code}
4) Run:
{code:java}
docker run -v /tmp/broker1.xml:/var/lib/artemis/etc/broker.xml --ti --rm --name
artemis1 -p 61616:61616 -p 8161:8161 -e ARTEMIS_USERNAME=admin -e
ARTEMIS_PASSWORD=admin
mirror-hub.docker.tech.lastmile.com/vromero/activemq-artemis:2.6.3-alpine
{code}
5) Run
{code:java}
docker run -v /tmp/broker2.xml:/var/lib/artemis/etc/broker.xml -ti --rm --name
artemis2 -p 61617:61617 -p 8162:8161 -e ARTEMIS_USERNAME=admin -e
ARTEMIS_PASSWORD=admin
mirror-hub.docker.tech.lastmile.com/vromero/activemq-artemis:2.6.3-alpine{code}
6) artemis1 will throw mentioned exceptions
