[jboss-jira] [JBoss JIRA] (WFLY-3965) Messaging: NullPointerException when http-acceptor and https-acceptor configured

Messaging: NullPointerException when http-acceptor and https-acceptor configured -------------------------------------------------------------------------------- Key: WFLY-3965 URL: https://issues.jboss.org/browse/WFLY-3965 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 8.1.0.Final Environment: Windows 7 Pro, Java 7u55 Reporter: Darren Jones Assignee: Jeff Mesnil Labels: JMS, Messaging With both an http-acceptor and an https-acceptor configured in the message subsystem, when an external Java app attempts to connect, it times out and the exception below appears in the server log. I tracked it down to the TransportConfigOperationHandlers.processAcceptors() method. At the end of the method, it creates a HashSet of the TransportConfiguration objects representing the acceptors. But, the TransportConfiguration equals() method reports that the https and http acceptors are equal, and as it is building a Set of unique values, the https-acceptor gets dropped. Later, when the http-upgrade handshake runs, the code is unable to find the https-acceptor, resulting in the NullPointerException. I think the fix might be to either not use a Set, or to look at the TransportConfiguration.equals() method. The workaround in the ticket works because the redundant <param> causes the equals() method to see the two acceptors as unequal. The exception was: [exec] 10:07:57,502 ERROR [org.xnio.listener] (default I/O-10) XNIO001007: A channel event listener threw an exception: java.lang.NullPointerException [exec] at org.jboss.as.messaging.HTTPUpgradeService$2.handleEvent(HTTPUpgradeService.java:161) [exec] at org.jboss.as.messaging.HTTPUpgradeService$2.handleEvent(HTTPUpgradeService.java:153) [exec] at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) [xnio-api-3.2.2.Final.jar:3.2.2.Final] [exec] at io.undertow.server.handlers.ChannelUpgradeHandler$1.handleUpgrade(ChannelUpgradeHandler.java:149) [exec] at io.undertow.server.protocol.http.HttpReadListener.exchangeComplete(HttpReadListener.java:271) [exec] at io.undertow.server.protocol.http.HttpServerConnection.exchangeComplete(HttpServerConnection.java:221) [exec] at io.undertow.server.HttpServerExchange.invokeExchangeCompleteListeners(HttpServerExchange.java:1131) [exec] at io.undertow.server.HttpServerExchange.terminateResponse(HttpServerExchange.java:1351) [exec] at io.undertow.server.Connectors.terminateResponse(Connectors.java:78) [exec] at io.undertow.server.protocol.http.ServerFixedLengthStreamSinkConduit.channelFinished(ServerFixedLengthStreamSinkConduit.java:33) [exec] at io.undertow.conduits.AbstractFixedLengthStreamSinkConduit.exitFlush(AbstractFixedLengthStreamSinkConduit.java:273) [exec] at io.undertow.conduits.AbstractFixedLengthStreamSinkConduit.flush(AbstractFixedLengthStreamSinkConduit.java:207) [exec] at org.xnio.conduits.ConduitStreamSinkChannel.flush(ConduitStreamSinkChannel.java:162) [xnio-api-3.2.2.Final.jar:3.2.2.Final] [exec] at io.undertow.channels.DetachableStreamSinkChannel.flush(DetachableStreamSinkChannel.java:100) [exec] at io.undertow.server.HttpServerExchange.closeAndFlushResponse(HttpServerExchange.java:1489) [exec] at io.undertow.server.HttpServerExchange.endExchange(HttpServerExchange.java:1470) [exec] at io.undertow.server.handlers.ChannelUpgradeHandler.handleRequest(ChannelUpgradeHandler.java:152) [exec] at io.undertow.server.handlers.ProxyPeerAddressHandler.handleRequest(ProxyPeerAddressHandler.java:45) [exec] at io.undertow.server.Connectors.executeRootHandler(Connectors.java:177) [exec] at io.undertow.server.protocol.http.HttpReadListener.handleEventWithNoRunningRequest(HttpReadListener.java:156) [exec] at io.undertow.server.protocol.http.HttpReadListener.handleEvent(HttpReadListener.java:91) [exec] at io.undertow.server.protocol.http.HttpReadListener.handleEvent(HttpReadListener.java:45) [exec] at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) [xnio-api-3.2.2.Final.jar:3.2.2.Final] [exec] at org.xnio.conduits.ReadReadyHandler$ChannelListenerHandler.readReady(ReadReadyHandler.java:66) [xnio-api-3.2.2.Final.jar:3.2.2.Final] [exec] at org.xnio.nio.NioSocketConduit.handleReady(NioSocketConduit.java:87) [xnio-nio-3.2.2.Final.jar:3.2.2.Final] [exec] at org.xnio.nio.WorkerThread.run(WorkerThread.java:539) [xnio-nio-3.2.2.Final.jar:3.2.2.Final]
