Installed current build of 6.x (today) on two nodes.

Previously had 2 nodes with 6.2, one of them configured to use a remote DC

copy the host.xml from the 6.2 to the 6.3 host controller and start the 6.3 HC

[Host Controller] 11:14:01,536 FATAL [org.jboss.as.host.controller] (Controller Boot Thread) JBAS010933: Host Controller boot has failed in an unrecoverable manner; exiting. See previous messages for details.


The issue/fix is easy:

org.jboss.as.host.controller.parsing;
public class HostXml extends CommonXml {
...
private void parseDomainController(...

line 922:

    case DOMAIN_1_5: {
      parseRemoteDomainController1_5(reader, address, expectedNs, list, false);
    }
    default: {
      parseRemoteDomainController1_5(reader, address, expectedNs, list, true);
      break;

=> missing break in the DOMAIN_1_5 and the parseRemoteDomainController1_5 method gets called a second time.

Will do a pull request right now
