    Starting Jboss 7 in debug mode fails. Dupplicate IPV6 address error.

      Hi everyone.

       

      So, I'm trying to connect Eclipse to a jboss 7 server I'm running in a CentOS virtual machine.

       

      I stopped the JBoss server and my terminal outputs the following from running /etc/init.d/jboss-eap-7 status

      jboss-eap is not running

       

      I followed the docs and uncommented the following line from standalone.conf:

      JAVA_OPTS="$JAVA_OPTS -agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n"

       

      journalctl -xn shows these lines at the end:

      -- All system services necessary queued for starting at boot have been

      -- successfully started. Note that this does not mean that the machine is

      -- now idle as services might still be busy with completing start-up.

      --

      -- Kernel start-up required 384878 microseconds.

      --

      -- Initial RAM disk start-up required 3109037 microseconds.

       

      But after I run /etc/init.d/jboss-eap-7 start, it fails outputting:

      Starting jboss-eap-7 (via systemctl):  Job for jboss-eap-7.service failed. See 'systemctl status jboss-eap-7.service' and 'journalctl -xn' for details.

                                                                 [FAILED]

       

      journalctl -xn displays the problem:

      Anyone came across this error?

       

      Thanks in advance.

       

      PS: recommenting the line @ standalone.conf and attempting to start the server, results in success:

      Starting jboss-eap-7 (via systemctl):                      [  OK  ]
