Intermittent NPE registering a slave HC in mixed-domain test suite

    XMLWordPrintable

Details

    Description

      I've occasionally seen test failures in the mixed domain tests when a testsuite cannot start because the slave HC can't register due to an NPE on the master:

      For example:

      http://brontes.lab.eng.brq.redhat.com/viewLog.html?buildId=82653&tab=buildResultsDiv&buildTypeId=WildFlyCore_PullRequest_WildFlyCoreFullIntegration
