Subject Re: Any known issues with Http Core NIO and tomcat 5.2.3?

Hi Supun, Oleg
> When a response is written back to the client the chunking was incorrect. All the communications
were done through HTTPS. Do you think the same problem is there in the client side of the
HTTPCore NIO as well?

I've encountered the following stack trace with 4.1-beta1 from a user 
over HTTP, which possibly indicates some issue with the chunk encoder. 
I've been trying to reproduce this with a test case, but I've not been 
able to yet.. Right now I'm fiddling with the test case for the chunk 
encoder to see how the limit of the buffer is exceeded..

Oleg - looking at the following trace, could you spot something here?

Supun - do you have a stacktrace when you say that the "chunking was 
incorrect" ?

thanks
