-----------------------------------
Resolution: Invalid
> NullPointerException in HttpConnection.isStale
> ----------------------------------------------
>
> Key: HTTPCLIENT-590
> URL: http://issues.apache.org/jira/browse/HTTPCLIENT-590
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 3.0.1
> Environment: Solaris 10, Sun JDK 1.4
> Reporter: Scott Battaglia
>
> We're getting the following exception when running HttpClient under
> relatively moderate load in a multithreaded environment (using the
> multithreaded manager). I looked at the line of code and it means either
> params is null or the socket is null. It doesn't look like params can either
> be null so I'm guessing its the socket (though I would assume the stale check
> would make sure the connection was opened at some point).
> Here's the stack trace:
