Unable to restart server group in domain mode

Restarting the servers in the standard domain.xml main-server-group will result in a hang in the CLI and in the master HC.

To reproduce start the standard domain.sh and in another window launch the CLI and:

[domain@localhost:9999 /] /server-group=main-server-group:restart-servers

Resulting console log output:
