Jitsi client Displays account full URI

@damencho
i’m using jitsi client , sending configuration thorough provisioning properties file , im unable to display name of account for jabber user , it shows entire usernname with domain like '123@xyz.jabber.com" and i want to display only 123 ,
i have given following properties for that

net.java.sip.communicator.impl.protocol.jabber.acc2.ACCOUNT_UID=Jabber:8845688@.xmpp.teledge.local
net.java.sip.communicator.impl.protocol.jabber.acc2.PASSWORD=********
net.java.sip.communicator.impl.protocol.jabber.acc2.USER_ID=8845688@
.xmpp.teledge.local
net.java.sip.communicator.impl.protocol.jabber.acc2.USER_NAME=4433
net.java.sip.communicator.impl.protocol.jabber.acc2.DISPLAY_NAME=test agentrep

DISPLAY_NAME does not seems to be working .
