Build Identifier: I'm using a ProxyServlet to proxy requests. This servlet handles many requests concurrently and these requests are often aborted mid-processing by the client from which the requests originate. Sometimes exception below is thrown and caught by ProxyServlet. ProxyServlet uses continuations. Could that be the problem ? Note that I do not see such problem if I switch from SelectChannelConnector to a regular SocketConnector. java.lang.IllegalArgumentException at java.nio.Buffer.position(Unknown Source) at java.nio.DirectByteBuffer.put(Unknown Source) at org.eclipse.jetty.io.nio.DirectNIOBuffer.poke(DirectNIOBuffer.java:201) at org.eclipse.jetty.io.nio.DirectNIOBuffer.poke(DirectNIOBuffer.java:141) at org.eclipse.jetty.io.AbstractBuffer.put(AbstractBuffer.java:457) at org.eclipse.jetty.http.HttpGenerator.addContent(HttpGenerator.java:216) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:167) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:101) at org.eclipse.jetty.io.AbstractBuffer.writeTo(AbstractBuffer.java:672) at org.eclipse.jetty.servlets.ProxyServlet$1.onResponseContent(ProxyServlet.java:455) at org.eclipse.jetty.client.HttpExchange$Listener.onResponseContent(HttpExchange.java:1172) at org.eclipse.jetty.client.AbstractHttpConnection$Handler.content(AbstractHttpConnection.java:332) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:872) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:235) at org.eclipse.jetty.client.AsyncHttpConnection.handle(AsyncHttpConnection.java:129) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.handle(SelectChannelEndPoint.java:585) at org.eclipse.jetty.io.nio.SelectChannelEndPoint$1.run(SelectChannelEndPoint.java:45) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:598) at org.eclipse.jetty.util.thread.QueuedThreadPool$1.run(QueuedThreadPool.java:533) Reproducible: Always Steps to Reproduce: - Instantiate jetty with a SelectChannelConnector and a ProxyServlet - have a client make many requests to the ProxyServlet while aborting some of them before they complete (unsure if the aborting is needed to trigger the problem).
I believe this issue has been fixed, although I'm not 100% sure as we don't have a reproduction of it. However, we did find some poor synchronisation of the pooled NIO buffers. Could you try a recent snapshot build from https://oss.sonatype.org/content/groups/jetty-with-staging/org/eclipse/jetty/jetty-distribution/7.6.0-SNAPSHOT/
