Openfire 3.10.3: unable to update Contact List (Roster) Sharing

Hello.

I update Openfire from 3.9.1 to 3.10.3 and unable to update Contact List (Roster) Sharing. With Openfire 3.9.1 all works fine. I found this in Openfire 3.10-rc changelog: "OF-869: Update Jetty to version 9.2"

When I try to update Contant List Sharing, I see error message in warn.log:

2015.12.04 09:55:29 org.eclipse.jetty.http.HttpParser - URI is too large >8192

2015.12.04 09:55:29 org.eclipse.jetty.http.HttpParser - badMessage: 414 for HttpChannelOverHttp@7288186e{r=0,c=false,a=IDLE,uri=-}

2015.12.04 09:55:29 org.eclipse.jetty.http.HttpParser - badMessage: java.lang.IllegalStateException: too much data after closed for HttpChannelOverHttp@7288186e{r=0,c=true,a=COMPLETED,uri=null}

I have a large number of groups (Total Groups: 151)

After search, I found jetty option: requestHeaderSize (Error when submitting large query strings – Lucidworks Support, Chapter 6. Configuring Jetty Connectors )

Can I apply this options to embedded openfire jetty component?
