FULL PRODUCT VERSION :
JVM: 1.7.0_09

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7600]

A DESCRIPTION OF THE PROBLEM :
When loading URLs from a particular server (possibly others but there is only one that I have come across with this issue so far) the headers give a null value for the " Set-Cookie " lines.

This only occurs in versions of the JRE after 1.7.0, including the very latest 1.7.0_09.

The headers from a wireshark trace produce the same, correct result as 1.7.0.

REGRESSION. Last worked in version 7

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Load this URL: http://secure.adnxs.com/seg?add=136880&t=2

Output the raw headers.

Two " Set-Cookie " lines will have the value " null " .

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The following are the headers from a wireshark trace:
