      JBoss EAP 7.3 Beta using on tests

      Added 7 servers to DC. See that the more the server the longer the time to load. Especially if these servers are in starting state.

      DC: ./domain.sh -b 0.0.0.0 -bmanagement 0.0.0.0

      SLAVE: ./domain.sh -Djboss.domain.master.address=IP_DC --host-config=host-slave.xml

      Currently, the web console is highly affected by the write lock acquisition. Most of the read operations done by the web console are translated into composite operations, that under some circumstances (target to a single host, non-wildcards..), require the DC write lock. This write lock acquisition has a huge impact on the web console since each operation is queued until the lock is released.

      As an example, if we have a deployment that takes some minutes in the middle the user is clicking to see the server status, soon the web console gets unresponsible.

      This issue tries to reduce the write lock acquisition in these cases and allow read operations.
