Intermittent failure of deployment containing two datasources in -ds.xml

      I prepared two deployments as simple as possible, one with two datasources showing the problem and one with single datasource added which doesn't cause the failure.

      Try to deploy them in a loop:

      for i in {1..100}; do 
  jboss-eap-7.0/bin/jboss-cli.sh -c --command="deploy two-datasources.jar --force"; 
done

      With two-datasources.jar some iterations will fail (cca 5 out of 100).
      When the debugger is attached to the server it fails almost everytime (95/100).

      Running smoke runs of JBossWS in EAP7, I occasionally hit test failure of WSRMStoreFeatureTestCase (from JBossWS testsuite). The testcase uses deployment that should add some datasources, but deploying ends up with:

      org.jboss.msc.service.StartException in service jboss.data-source.java:jboss/datasources/rmclientdb.statistics: Failed to start service

      After some debugging, the problematic scenario seems to be:
      1) there is a deployment (jar/war, doesn't matter) containing -ds.xml configuration file
      2) this file contains definition of at least two datasources to be added

        1. two-datasources.jar
          0.7 kB
        2. one-datasource.jar
          0.7 kB
