Description of problem:
Using HTTP PUT while having webdav enabled causes java.nio.BufferOverflowException on JDK 1.7 and newer (probably connected to NIO2 connector) [1]

Version-Release number of selected component (if applicable): EAP 6.3.0.DR6


How reproducible: always


Steps to Reproduce:
1. enable webdav + set read-only to false in static configuration of web subsystem
   * /subsystem=web/configuration=static-resources:write-attribute(name=webdav, value=true)  
   * /subsystem=web/configuration=static-resources:write-attribute(name=read-only, value=false)
2. deploy some webapp (e.g. called webdav.war)
3. use sardine and do PUT request (SardineFactory.begin().put(http://localhost:8080/webdav/date.txt, new Date().toString().getBytes());

Actual results: org.apache.http.NoHttpResponseException: The target server failed to respond (on client) and [1] on server

Expected results: date.txt appears on the specified url => successful PUT request

Additional info:
I wasn't able to reproduce it using CURL that's why I suggest using sardine where I am getting this response everytime (other webdav operations work just fine)
