Wildfly 12 : jboss-cli.sh in infinite loop

i cannot use anymore the jboss-cli.sh to connect to the contoller since i migrated from v11 to 12:

wildfly@java2:/opt/Wildfly$ ls -la

drwxr-xr-x 1 root root 156 Mar 3 20:36 jboss-server-migration

drwxr-xr-x 1 root root 454 Mar 4 00:09 overlays

drwxr-xr-x 1 root root 166 Mar 4 11:43 scripts

drwxr-xr-x 1 root root 236 Oct 24 05:30 wildfly-11.0.0.Final

drwxr-xr-x 1 root root 236 Mar 1 07:29 wildfly-12.0.0.Final

lrwxrwxrwx 1 root root 20 Mar 4 12:49 wildfly-current -> wildfly-12.0.0.Final

my wildfly management console is on 172.20.12.192.

v12 has been migrated from v11 with the jboss-server-migration tool. Applications and app manager works fine and the wildfly instance controller is well binded on the requested ip.

with wildfly-current link on -> wildfly-11.0.0.Final:

this works perfectly:

(cd /opt/Wildfly/wildfly-current/bin && ./jboss-cli.sh -c -u=xx -p=xx --controller=http-remoting://172.20.12.192:9990)

with wildfly-current -> wildfly-12.0.0.Final:

this go in infinite loop until crash :

(cd /opt/Wildfly/wildfly-current/bin && ./jboss-cli.sh -c -u=xx -p=xx --controller=http-remoting://172.20.12.192:9990)

output:
