Sam Berlin commented on HTTPCLIENT-776:
---------------------------------------
Looks like this change:
http://fisheye6.cenqua.com/browse/httpcomponents/httpclient/trunk/module-client/src/main/java/org/apache/http/impl/conn/AbstractClientConnAdapter.java?ignore1=B&ignore2=b&r1=652020&r2=652945&u=3
caused it. I think the change is a good one, but had the side effect of
causing tracker to be nulled out, which exposes the problem.
