Fwd: NullPointerException in websocket endpoint onerror
We're seeing the following issue with a websocket endpoint on tomcat 8.0.15 when OnError tries to close the websocket session. What could be the problem? java.lang.reflect.InvocationTargetException at sun.reflect.GeneratedMethodAccessor91.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.tomcat.websocket.pojo.PojoEndpointBase.onError(PojoEndpointBase.java:134) at org.apache.tomcat.websocket.server.WsHttpUpgradeHandler.onError(WsHttpUpgradeHandler.java:167) at org.apache.tomcat.websocket.server.WsHttpUpgradeHandler.access$300(WsHttpUpgradeHandler.java:48) at org.apache.tomcat.websocket.server.WsHttpUpgradeHandler$WsReadListener.onError(WsHttpUpgradeHandler.java:228) at org.apache.coyote.http11.upgrade.AbstractServletInputStream.onError(AbstractServletInputStream.java:209) at org.apache.coyote.http11.upgrade.Nio2ServletInputStream$1.failed(Nio2ServletInputStream.java:76) at org.apache.coyote.http11.upgrade.Nio2ServletInputStream$1.failed(Nio2ServletInputStream.java:49) at sun.nio.ch.Invoker.invokeUnchecked(Invoker.java:128) at sun.nio.ch.Invoker$2.run(Invoker.java:218) at sun.nio.ch.AsynchronousChannelGroupImpl$1.run(AsynchronousChannelGroupImpl.java:112) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException at org.apache.tomcat.websocket.server.WsRemoteEndpointImplServer.onWritePossible(WsRemoteEndpointImplServer.java:96) at org.apache.tomcat.websocket.server.WsRemoteEndpointImplServer.doWrite(WsRemoteEndpointImplServer.java:81) at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.writeMessagePart(WsRemoteEndpointImplBase.java:444) at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.startMessage(WsRemoteEndpointImplBase.java:335) at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.startMessageBlock(WsRemoteEndpointImplBase.java:264) at org.apache.tomcat.websocket.WsSession.sendCloseMessage(WsSession.java:536) at org.apache.tomcat.websocket.WsSession.doClose(WsSession.java:464) at org.apache.tomcat.websocket.WsSession.close(WsSession.java:441) at com.testEndpoint.onWebSocketError(WebsocketEndpoint.java:52)
Issues with log4j.core.async.AsyncLoggerContextSelector when upgrading from 8.0.15 to 8.0.18
I've recently upgraded from 8.0.15 to 8.0.18 and I have a new problem which I didn't have on 8.0.15. The configuration of tomcat and my application remained exactly the same when upgrading. When running tomcat with -DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector (defined in setenv.sh) to enable log4j2's async logging, I now get a ClassNotFoundException (see below). What could be the problem?

RE: Issues with log4j.core.async.AsyncLoggerContextSelector when upgrading from 8.0.15 to 8.0.18
setenv.sh does have an extra "\r" but the same file worked for me on 8.0.15 - I only copied it from the older tomcat. I removed it and now it works on 8.0.18 too. thank you.
