Hi, I am trying to build a Streaming solution on top of Tomcat and using Async servlets. What I am doing is I start an asynchronous process using `startAsync()` and then attach a ReadListener which streams the data forward `onDataAvailable`, the consumer consumes this on another thread. Now the problem I am running into is if the there is a SocketTimeoutException during the read, onError of ReadListener is triggered and I pass that forward, however I don't call AsyncContext.complete, because I want the async thread processing the data to be first able to deal with the exception and then I close it on the async thread when its done.
However what I am observing is irrespective of if my not closing the context, it's closed by default by Tomcat and the request/response objects are recycled. Due to this during the error handling when I am trying to read some headers I get a IllegalStateException. I don't want to do the clean up on the IO thread since it can be heavy and I don't want to overwhelm the IO threads. Is there a way around this, to keep the async context open even on an error and not close it till complete is invoked? Thanks, Adwait.
