This works for "main-server-group", but for some reason isn't working for "other-server-group":

[domain@localhost:9999 /] /host=local/server-config=server-three:start
{
"outcome" => "success",
"result" => "STARTING",
"compensating-operation" =>

{ "operation" => "stop", "address" => undefined, "name" => "server-three" }

}
[domain@localhost:9999 /] /server-group=other-server-group/deployment=test-application.war:add
{
"outcome" => "success",
"result" => undefined,
"compensating-operation" =>

{ "operation" => "remove", "address" => [ ("server-group" => "other-server-group"), ("deployment" => "test-application.war") ] }

}
[domain@localhost:9999 /] /host=local/server=server-three:read-children-name(child-type=deployment)
{
"outcome" => "failed",
"failure-description" => "No handler for read-children-name at address []"
}
[domain@localhost:9999 /] /host=local/server=server-three:read-children-names(child-type=deployment)
{
"outcome" => "success",
"result" => [],
"compensating-operation" => undefined
}
[domain@localhost:9999 /] /server-group=other-server-group/deployment=test-application.war:add
{
"outcome" => "failed",
"failure-description" =>

{"domain-failure-description" => [("java.lang.IllegalStateException" => "Resource at address [ (\"server-group\" => \"other-server-group\"), (\"deployment\" => \"test-application.war\") ] already exists")]}

}
