java.lang.IllegalStateException: Calling [asyncComplete()] is not valid for a request with Async state [COMPLETING]

[Vicky]

Hi Folks,

I am using Tomcat 7.0.42, in embedded mode, using NIO connector. Running on
a linux box.

I use request.startAsync() to create an AsyncContext. And call complete()
once everything is done. But complete() is called via a separate thread.

Any idea why am i getting this exception?

Thanks,
Vicky
