AsyncRequestNotUsableException thrown and logged after upgrade from Spring Boot 3.2.3 to Spring Boot 3.2.4

[vap78]

Hi

after upgrading to spring boot 3.2.4 from 3.2.3 our applications start logging this exception over and over (I suspect on every request):

this did not happen with the 3.2.3 version and after a rollback the exceptions are no longer logged.

The exceptions themselves do not seem to have any functional impact.

Used JVM: Amazon Corretto JDK 21.0.2

The change in behavior is due to #32340. We'll transfer this to Spring Framework so that they can investigate further.

What's actually logging the exception?

Previously, this would have been org.apache.catalina.connector.ClientAbortException. It is now wrapped with AsyncRequestNotUsableException, and that should be handled in DefaultHandlerExceptionResolver by marking it resolved without further handling.

Hi

looks like this is traced in a custom exception handler annotated with @ControllerAdvice.

What is the recommendation here?

I could simply ignore this specific exception, but what would be the performance impact of exceptions being generated/thrown on every request?

Best regards
Vasil

[rstoyanchev]

In this case the exception only wraps the IOException from the Servlet response. In other words there is already an exception, and such exceptions should be raised only when something goes wrong with the network, not for every request.

The exception implies the response is no longer usable, and you can't send any more data. You can treat it in the same way that you would the underlying ClientAbortException or any IOException from the response.

I'm closing as there is nothing for us to do, but feel free to comment if necessary.

How did you solve it？I am facing the same problem. Thanks.

We are also seeing this error after an upgrade, it doesn't seem to happen for every request, just those that have used response.sendRedirect(...). In our case we just see 'Response not usable after response errors.' logged with a nasty error message (no IO errors)... the client gets the redirect, so the issue is only server side...

We didn't .

The only solution I see is to suppress the exception in the custom exception handler.
But I don't understand, why is it being thrown as we did not changes, except the Spring boot upgrade.

[vap78]

From what I see what has changed is the exception type thrown.

Before spring-web:6.1.5 a ClientAbortException was thrown. Since 6.1.5 a AsyncRequestNotUsableException.

So adding AsyncRequestNotUsableException to the exception handler will restore the old state.

[namannigam]

We faced a similar issue. From this thread, I am taking away that we would either have to handle the AsyncRequestNotUsableException similar to other exceptions in the ControllerAdvice or have to live with it and look for resolution as any other IOException. Is that right @vap78 @rstoyanchev ?
