Olivier Lafontaine updated HTTPCLIENT-1715:
-------------------------------------------
    Summary: NTLMEngineImpl.Type1Message not thread safe but declared as a constant  \
(was: NTLMEngineImpl.Type1Message not thread safe but declared as a singleton)

> NTLMEngineImpl.Type1Message not thread safe but declared as a constant
> ----------------------------------------------------------------------
> 
> Key: HTTPCLIENT-1715
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1715
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.5.1
> Reporter: Olivier Lafontaine
> 
> {{NTLMEngineImpl}} declares a {{static final}} member named {{TYPE_1_MESSAGE}} of \
> type {{Type1Message}}. Members of {{Type1Message}} are final and do not change, but \
> that is not the case for members of its superclass {{NTLMMessage}}. Whenever the \
> method {{NTLMEngineImpl#getType1Message(String, String)}} is called, the method \
> {{NTLMMessage#getResponse()}} get called on the {{TYPE_1_MESSAGE}} instance and \
>                 this modifies the following members of {{NTLMMessage}}:
> * messageContents
> * currentOutputPosition
> This is not thread safe and we get exceptions as seen in HTTPCLIENT-1686.
> My guess is that the computed response string should be kept in a constant instead \
> of a {{Type1Message}} instance.
