-----------------------------------------------
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.
