OpenJDK HTTP Client Bug

[Chris Hegarty]

[bcc'ing off jdk7-dev at openjdk.java.net, and including 
net-dev at openjdk.java.net]

Hi Stuart,

Thanks for reporting this issue.

It does indeed look like a regression/side-effect of that recent change. 
There is no sign of your attached patch, maybe it got stripped by 
mailman. You can probably just post it inline.

Thanks,
-Chris.
