                 Key: CAMEL-9070

    Affects Versions: 2.15.2
            Reporter: Ralf Steppacher


When using the jetty component in a simple reverse proxy route deployed in {{Karaf 3.0.3}} I randomly receive the following Stacktrace:

{noformat}

I have found (rather old) posts on the web that claim that the behavior is related to message size. I am {{POST}}-ing about 6kb of SOAP XML with the following headers:

{noformat}
POST http://localhost:8080/XDS3/repository/repo2 HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: multipart/related; type="application/xop+xml"; start="<ro...@soapui.org>"; start-info="application/soap+xml"; action="urn:ihe:iti:2007:RetrieveDocumentSet"; boundary="----=_Part_139_1471895036.1439218177147"
MIME-Version: 1.0
Content-Length: 6858
Host: localhost:8080
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

The issue pops up at random but not evenly distributed. It either almost always happens or hardly ever. Re-installing my bundle or restarting Karaf usually triggers a switch between the two scenarios.
