JBoss EAP web management console won't load while domain host/slave controller is starting

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 7.1

Issue

• In EAP 7.1 domain environment, web management console (on domain/master controller) shows HTTP response 500 error while any host/slave controller is in booting up state.
• EAP web management console shows follow error message:

Unexpected HTTP response: 500

Request
{
    "address" => [],
    "operation" => "read-children-resources",
    "child-type" => "host"
}

Response

Internal Server Error
{
    "outcome" => "failed",
    "rolled-back" => true
}

• We ca not access JBoss EAP web console. The user and password prompt appears, we can fill it and send, but it freezes on loading screen. We tried to restart the JBoss EAP, but the problem persists.

Resolution

This is reported as a bug Content from issues.jboss.org is not included.JBEAP-16214 and will be fixed in future releases.

Root Cause

Operation :read-children-resources(child-type=host) could not handle the scenario correctly while a host is in booting phase.
