Description of problem: Experiencing BUFFER_OVERFLOW in JBoss when using NIO. Buffer is not expanded so request fails.


Version-Release number of selected component (if applicable): 6.4.0


How reproducible: Always, when using NIO and HTTPS.


Steps to Reproduce:
1. Use org.apache.coyote.http11.Http11NioProtocol and HTTPS
2. Make a request that has a packet size 16KB+ 
3. Check logs for "BWEB003064: Error during blocking read: java.io.IOException: JBWEB002048: Unable to unwrap data, invalid status 
BUFFER_OVERFLOW"

Actual results: Failure to process request, resulting in failed request 


Expected results: Expected request to succeed just as it would if not using NIO 


Additional info:

Issue happens even when using `-Djsse.SSLEngine.acceptLargeFragments=true`.

I'll attached the .war I used to reproduce.
