Description
Natives [1] for ActiveMQ Artemis are not loaded during start of EAP server.
To reproduce:
1. Download EAP 7.0.0.DR8 and unzip - http://download.lab.bos.redhat.com/devel/candidates/JBEAP/JBEAP-7.0.0.DR8/jboss-eap-7.0.0.DR8.zip
2. Delete all natives in org.apache.activemq.artemis module. This step is necessary as currently there already are natives in EAP zip.
- rm -rf $JBOSS_HOME/modules/system/layers/base/org/apache/activemq/artemis/main/lib/*
3. Download and unzip natives for your platform over EAP directory - http://download.lab.bos.redhat.com/devel/candidates/JBEAP/JBEAP-7.0.0.DR8-artemis-natives/natives/
4. Modify standalone-full-ha.xml - add <journal type="ASYNCIO" /> between <server name="default"> ... </server> tags in messaging-activemq subsystem
5. Start server by: sh standalone.sh -c standalone-full-ha.xml
Natives are NOT loaded and info message:
