solution RE: request.getSession() generates IllegalStateException in top filter(appears, response not being recycled properly if SocketException happenedfor it in the past)

[Leonard Gestrin <Le...@markettools.com>]

I found a solution that seems to hold.

Instead of associating ImageWriter directly with response.outputstream, I create temporary ByteInputStream that is associated with javax.imageio.ImageWriter 

Once imagewriter is done, I am dumping ByteInputStream bytes to  response.outputsream.

My theory is that ImageWriter was hanging to outputstream longer than it supposed to 
And that was causing issues in "ClientAbortException" cases.

Thanks

It's not completely clear from your description whether the filter is part of the request that encountered the socket error or a different request.  If the former, the behavior you observe is expected; if the latter, you may be running into this bug, fixed over a year ago:

What happens if you try it on a version that's not over 2.5 years old?
