Hi, I have a question about Async state DISPATCHING.
I have the following scenario - Application invokes startAsync() and then continues processing in a separate non-container thread A. - At some point thread A makes dispatch() -> Async state is changed to DISPATCHING - At the same time a socket error occurs and thread B tries to change the Async state to ERROR, as the state was already changed to DISPATCHING, the exception below occurs and the state cannot be changed to ERROR. Isn't that a problem as onError event will not be called? Why don't we treat DISPATCHING as DISPATCHED in asyncError? https://github.com/apache/tomcat/blob/trunk/java/org/apache/coyote/AsyncStateMachine.java#L388 Thanks, Violeta org.apache.catalina.connector.CoyoteAdapter.asyncDispatch Exception while processing an asynchronous request java.lang.IllegalStateException: Calling [asyncError()] is not valid for a request with Async state [DISPATCHING] at org.apache.coyote.AsyncStateMachine.asyncError(AsyncStateMachine.java:398) at org.apache.coyote.AbstractProcessor.action(AbstractProcessor.java:393) at org.apache.coyote.Request.action(Request.java:390) at org.apache.catalina.core.AsyncContextImpl.setErrorState(AsyncContextImpl.java:385) at org.apache.catalina.connector.CoyoteAdapter.asyncDispatch(CoyoteAdapter.java:175) at org.apache.coyote.AbstractProcessor.dispatch(AbstractProcessor.java:225) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:53) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:796) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1366) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745)
