Hi, I'm writing an http server for Ceylon on top of undertow. All bytes are written to response and successfully transferred, but exception bellow occurs when shutdownWrites is called. Stepping through a "write" method of FixedLengthStreamSinkChannel, looks like "state" is not updated correctly, it is always subtracted only for are number of bytes written in one loop. Am I missing something or is it a bug ? byte array size is 6919638, usually there are 147456 bytes written to a response in a loop My code for writing bytes to response ... not quite Java, but readable ;) shared actual void writeBytes(Array<Integer> bytes) { //ByteBuffer.wrap value bb = wrapByteBuffer(bytes); value response = getResponse(); variable Integer remaining := bytes.size; while (remaining> 0) { variable Integer written := 0; while((written := response.write(bb))> 0) { remaining -= written; try { response.awaitWritable(); } catch(JIOException e) { //TODO print(e); } } } } Exception in thread "XNIO-1 task-2" java.lang.Error: org.xnio.channels.FixedLengthUnderflowException: 6815744 bytes remaining at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1116) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) Caused by: org.xnio.channels.FixedLengthUnderflowException: 6815744 bytes remaining at org.xnio.channels.FixedLengthStreamSinkChannel.shutdownWrites(FixedLengthStreamSinkChannel.java:291) at ceylon.net.httpd.internal.HttpResponseImpl.responseDone(HttpResponseImpl.ceylon:71) at ceylon.net.httpd.internal.CeylonRequestHandler$AsyncInvoker$1completionHandler_.handleComplete(CeylonRequestHandler.ceylon:56) at ceylon.net.httpd.endpoints.StaticFileEndpoint.service(StaticFileEndpoint.ceylon:50) at ceylon.net.httpd.internal.CeylonRequestHandler$AsyncInvoker.run(CeylonRequestHandler.ceylon:60) at io.undertow.util.WorkerDispatcher$1.run(WorkerDispatcher.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) ... 2 more Thanks, Matej. _______________________________________________ undertow-dev mailing list undertow-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/undertow-dev

I updatetd to XNIO 3.1.0.Beta7 and latest Undertow master.
