Jetty configuration - requestHeaderSize in camel-cxf

Issue

• We are running into a problem with a CXF endpoint that receives large headers.
  The setup is:
  • jboss-fuse 6.1.0
  • An osgi (blueprint) bundle with the following configuration:

  <cxf:rsServer id="someEndpoint" address="http://localhost:8080/domain/test/link"  serviceClass="com.redhat.ServiceEndpoint" ></cxf:rsServer>

• The error we get with large headers is HTTP 413 - FULL.

In the logs:

2015-06-11 10:33:43,202 | WARN  | tp2098740307-177 | HttpParser                       | ?                                   ? | 93 - org.eclipse.jetty.aggregate.jetty-all-server - 8.1.14.v20131031 | HttpParser Full for SCEP@733a331{l(/0:0:0:0:0:0:0:1:49339)<->r(/0:0:0:0:0:0:0:1:8080),s=1,open=true,ishut=false,oshut=false,rb=false,wb=false,w=true,i=0r}-{AsyncHttpConnection@767e3d2c,g=HttpGenerator{s=0,h=-1,b=-1,c=-1},p=HttpParser{s=-1,l=6002,c=-3},r=0}

• We know this could be solved by setting the requestHeaderSize property on the connector (jetty). We tried different settings in the blueprint.xml (httpj:engine, httpj:connector, etc.) but the setting is not used when the buffer is constructed.
  We debugged the Fuse runtime and set the property manually in the SelectChannelSelector._buffers._headerSize variable. The headers are then correctly parsed.
  Currently, we try to do this in blueprint.xml as follows (note: this doesn't work):

    <httpj:engine-factory bus="cxf">
        <httpj:engine port="8080">
            <httpj:connector>
                <bean class="org.eclipse.jetty.server.nio.SelectChannelConnector">
                    <property name="port">8080</property>
                    <property name="requestHeaderSize" value="80000"></property>
                    <property name="requestBufferSize" value="80000"></property>
                </bean>
            </httpj:connector>
        </httpj:engine>
    </httpj:engine-factory> 

• Can you tell me where to configure the requestHeaderSize for the jetty instance used by CXF ?
