Has anyone else seen this error before?

It happens when I have ClientPNames.HANDLE_REDIRECTS = true and I hit a
server which 302s me to another URL. I'm using the following versions... so
maybe upgrading to the latest dev versions of client would help:

      <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpcore</artifactId>
        <version>4.2-beta1</version>

      </dependency>

Thanks in advance...
