Admin console shows incorrect value for attribute when value set to -1 in EAP 6

Issue

• connection-ttl and reconnect-attempts are set to -1 domain.xml

                   <client-failure-check-period>2147483646</client-failure-check-period>
                            <connection-ttl>-1</connection-ttl>
                            <reconnect-attempts>-1</reconnect-attempts>

But in the admin console, I got the information which is not match with the configuration file. Why this behaviour and which is correct value of above parameters ?
