------------------------------------
Summary: Continuation frame doesn't copy payload when receiving
large headers
Key: HTTPCORE-772
URL: https://issues.apache.org/jira/browse/HTTPCORE-772
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore NIO
Affects Versions: 5.3.1
Reporter: Shang Xiang
h1. Expected Behavior
When receiving large headers, the payloads of several frames are copied into
the {{Continuation}} object and then the headers are decoded in one go once the
{{END_HEADERS}} frame is received.
h1. Observed Behavior
The {{Continuation::copyPayload}} method updates the underneath array of its
{{headerBuffer}} but never updates the pointer. Therefore the copying action is
of no effect and eventually the headers cannot be decoded.
h1. Reproduction
Having the server respond many headers with large values such that they were
split into multiple frames.
The client will not be able to receive the response due to failure to decode
the headers.
