to problem with Jetty buffer size http://jira.codehaus.org/browse/JETTY-336
Yes, we now send big header during the handshake op

The solution is to increase buffer size (as mentioned at the end of the issue) using
<Set name='headerBufferSize'>8192</Set>
in connector section of jetty.xml, however we don't use static jetty.xml file and http://cargo.codehaus.org/Jetty+6.x doesn't support dynamic setting of this attribute.
Tomcat doesn't suffer from the same issue.
