Symptom:
Voicemail disconnected on new message with display name in UTF-8

Conditions:
For a user with a display name in UTF 8 encoding (e.g Андрей Андреев), the request application/json from Jetty Port 7080 to Jabber Client gets truncated. The voice mails sent to him from ASCII Display Name show up right away, but UTF-8 Display Name show up with 2 minutes delay.
This 2 minute delay is caused due to formatted json notification truncation happening at UC side. When we encounter something like ...":"/meta/connec   this is judged to be a network issue and connection to UC is restarted.
Jabber client gets incomplete/truncated Request from CUC and performs a restart and a new subscription id is generated for the user :
