Testing env: 32bit winxp, jre 8 nightly #604

Steps to reproduce:
- clear dep_user_home/security dir
- deploy http://rehte.cn.oracle.com:8080/wshost/new_framework/new_framework/tests/javaws/blacklist/lib/bl_cert to localhost like
http://localhost:8080/blacklist/classes/blacklisted.certs
- add following properties in deployment.properties file
deployment.blacklisted.certs.url=http\://localhost\:8080/blacklist/classes/blacklisted.certs
- invoke "javaws -SSVBaselineUpdate"
- if file dep_user_home/security/blacklisted.certs is not downloaded, bug is reproduced.

This bug is reproduced from 8 nightly #604, it's working with #603

Because all our cases are deployed on localhost, it affects all our dynamic blacklist cases and blacklisted cert cases
