Description bdevaney 2014-04-01 19:32:35 UTC 
Generated with the NIO2 protocol in the connector.  The same code using tomcat with HTTP/1.1 and AJP/1.3 in the connector worked correctly.

Comment 1 Remy Maucherat 2014-04-01 22:43:05 UTC 
The AJP connector is really heavy on code reuse, so the NIO2 code that is used here is identical to the NIO1 code (and the shared code looks like it's only working by accident, so I'll try to fix it http://svn.apache.org/r1583814 ).

You could investigate and debug to see why this exception occurs or test the fix.
Comment 2 Remy Maucherat 2014-04-03 12:37:23 UTC 
No feedback, so assume fixed by r1583814
