Where the same thing works with jdk 1.6 update 14.

We tried to unzip the file liferay-portal-tomcat-6.0-5.2.3 of liferay.com (it was dowloaded locally and tried to unzip using local dir path).
The size of this file is 138 mb.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
use <unzip> with this file using ant, it would fail

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It is supposed to unzip as the zip file is a valid zip file and works fine in jdk 1.6 update 14 and also using winzip.
ACTUAL -
fails with exception
