----------------------------------------------
Summary: New JAXB tests in WFLY-13968 fails on ee9 profile
Key: WFLY-14243
URL: https://issues.redhat.com/browse/WFLY-14243
Project: WildFly
Issue Type: Bug
Components: Test Suite
Reporter: Ricardo Martin Camarero
Assignee: Ricardo Martin Camarero
The new JAXB tests introduced in WFLY-13968 fails when using the ee9 profile:
* org.jboss.as.test.integration.jaxb.unit.JAXBContextSystemPropCustomTestCase
* org.jboss.as.test.integration.jaxb.unit.JAXBContextUsingPropertiesTestCase
The reason is that in ee9 the system property and the keys inside the {{jaxb.properties}} file needs to be prefixed by {{jakarta}} instead of {{javax}}.

Hi.
there are to be 2 servers and haproxy between them.
[wildfly-server1] <-> [haproxy] <-> [wildfly-server2]
there are to be defined remote connections to haproxy server
like this:
{code}
<http-connector name="http-remoting-connector" connector-ref="default" security-realm="ApplicationRealm"/>
<outbound-connections>
<remote-outbound-connection name="remote-ejb-connection" outbound-socket-binding-ref="remote-ejb" protocol="http-remoting" security-realm="ejb-security-realm" username="ejb">
<properties>
<property name="SASL_POLICY_NOANONYMOUS" value="false"/>
<property name="SSL_ENABLED" value="false"/>
</properties>
</remote-outbound-connection>
</outbound-connections>
{code}
{code}
<outbound-socket-binding name="remote-ejb">
<remote-destination host="test-ejb-balance01" port="30001"/>
</outbound-socket-binding>
{code}
haproxy.cfg
{code}
### start config for haproxy_host.name balance
frontend balance_test-wf01
bind 192.168.230.13:30000
mode tcp
default_backend test-wf01_servers
option tcplog
log global
capture request header X-Forwarded-For len 15
backend test-wf01_servers
balance roundrobin
server server-test-wf01 test-wf01:8080 check
### stop config for haproxy_host.name balance
### start config for haproxy_host.name balance
frontend balance_test-wf02
bind 192.168.230.13:30001
mode tcp
default_backend test-wf02_servers
option tcplog
log global
capture request header X-Forwarded-For len 15
backend test-wf02_servers
balance roundrobin
server server-test-wf02 test-wf02:8080 check
### stop config for haproxy_host.name balance
{code}
You can see tcp mode in *haproxy.cfg*, but I'd tried even http mode.
In order to reproduce this scheme I deployed application which calls remote-ejb on wildfly-server2.
When wildfly-server2 is online there are no problems.
But if I'll shutdown wildfly there I'll have situation I described before.
