It is difficult to make a definitive statement as to what the cause of
the problem might without having at least some sort of contextual
details. By the look of it, for some reason a connection ended up in a
inconsistent state. This quite likely to be due to a bug in
HttpAsyncClient but I cannot say for sure. Could you please raise a JIRA
for this defect and try to provide some context details about what kind
of requests the client has been executing when the problem occurred?
