Improve error reporting on misconfigured security-realm ------------------------------------------------------- Key: WFCORE-975 URL: https://issues.jboss.org/browse/WFCORE-975 Project: WildFly Core Issue Type: Enhancement Components: Domain Management, Security Reporter: Alessio Soldano Assignee: Tomaz Cerar Priority: Minor Fix For: 2.0.10.Final I've erroneously configured standalone.xml with an empty (no child) security realm and referenced it in a undertow https listenerer. When running a test relying on https, I'm getting the following error only on server side: 11:43:44,482 ERROR [org.xnio.listener] (default I/O-3) A channel event listener threw an exception: java.lang.NullPointerException at org.xnio.ssl.AbstractAcceptingSslChannel.accept(AbstractAcceptingSslChannel.java:143) [xnio-api-3.1.0.CR2.jar:3.1.0.CR2] at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:288) [xnio-api-3.1.0.CR2.jar:3.1.0.CR2] at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:285) [xnio-api-3.1.0.CR2.jar:3.1.0.CR2] at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:91) [xnio-api-3.1.0.CR2.jar:3.1.0.CR2] at org.xnio.ChannelListeners$DelegatingChannelListener.handleEvent(ChannelListeners.java:1052) [xnio-api-3.1.0.CR2.jar:3.1.0.CR2] at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:91) [xnio-api-3.1.0.CR2.jar:3.1.0.CR2] at org.xnio.nio.NioTcpServerHandle.handleReady(NioTcpServerHandle.java:53) [xnio-nio-3.1.0.CR2.jar:3.1.0.CR2] at org.xnio.nio.WorkerThread.run(WorkerThread.java:528) [xnio-nio-3.1.0.CR2.jar:3.1.0.CR2]
