[undertow-dev] ProxyHandler timeout handling

[Stuart Douglas]

This looks like a bug, can you file a JIRA? It looks like it is still
attempting to associate a connection with the request after the
request has timed out.

This will not affect the functionality, but will result in annoying
log messages.
