Summary: "HTTPS proxy SSL engine" java.lang.NullPointerException

Initial Comment:
I'm running the grinder 3.6 tcpproxy via HotSpot 1.6 on windows, pointing at an internal proxy server, and then loading an http page which in turn loads some external 3rd party https resources.

It consistently fails to load the https resources and logs the NPE below.

I've looked at the code and it seems to suggest HTTPSProxySocketFactory.m_nextRawClientSocket is null (but then I can't see why it wouldn't be). I'm no sure how to progress diagnosing this.

java grinder.TCPProxy -console -http -localport 8000 -httpproxy xxxxxx 8080
