-----------------------------------------------

             Summary: GPF occurs when WindowsNegotiateScheme.dispose() is called by garbage
collector
                 Key: HTTPCLIENT-1681
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1681
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.5
         Environment: Windows 7
            Reporter: Alexander Bernstein


I am using WindowsNegotiateScheme (created by WindowsNegotiateSchemeFactory) to have my client
authenticate using SPNEGO.

During the auth dance, several instances of WindowsNegotiateScheme are created. At a later
time (arbitrary) these objects are finalized by GC, which causes a GPF and a crash.
