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).

    Description

      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

	... 3 more

      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

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
