Hello, I am working with Apache's HTTP async client and have encountered a possible bug (race condition).
PROBLEM: While accessing a nonexistent file on the server, I would ALWAYS expect to receive a "404 : component not found" error message. However, the behavior is sporadic. Sometimes I receive the correct message, whereas, on the other occasions it throw the following exception: org.apache.http.impl.nio.client.LoggingAsyncRequestExecutor exception SEVERE: http-outgoing-1 [ACTIVE] HTTP protocol exception: An established connection was aborted by the software in your host machine java.io.IOException: An established connection was aborted by the software in your host machine at sun.nio.ch.SocketDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:43) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:225) at sun.nio.ch.IOUtil.read(IOUtil.java:198) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:359) at org.apache.http.impl.nio.reactor.SessionInputBufferImpl.fill(SessionInputBufferImpl.java:97) at org.apache.http.impl.nio.codecs.AbstractMessageParser.fillBuffer(AbstractMessageParser.java:115) at org.apache.http.impl.nio.DefaultNHttpClientConnection.consumeInput(DefaultNHttpClientConnection.java:167) at org.apache.http.impl.nio.DefaultHttpClientIODispatch.onInputReady(DefaultHttpClientIODispatch.java:125) at org.apache.http.impl.nio.DefaultHttpClientIODispatch.onInputReady(DefaultHttpClientIODispatch.java:50) at org.apache.http.impl.nio.reactor.AbstractIODispatch.inputReady(AbstractIODispatch.java:112) at org.apache.http.impl.nio.reactor.BaseIOReactor.readable(BaseIOReactor.java:160) at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvent(AbstractIOReactor.java:342) at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvents(AbstractIOReactor.java:320) at org.apache.http.impl.nio.reactor.AbstractIOReactor.execute(AbstractIOReactor.java:280) at org.apache.http.impl.nio.reactor.BaseIOReactor.execute(BaseIOReactor.java:106) at org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor$Worker.run(AbstractMultiworkerIOReactor.java:604) at java.lang.Thread.run(Thread.java:722) java.io.IOException: An established connection was aborted by the software in your host machine INVESTIGATION: I downloaded the source code and tried to investigate it myself. Interestingly, I found that the "IOReactorStatus" is set to "SHUTDOWN_REQUEST" only after the exception has already been thrown. I am not sure if this is the root cause or not, but I would highly appreciate if somebody could please confirm if it's a known issue and if there exists a solution. Thanks, Poonam
