jar update with downloading extension in background not working in 6u18 b07.

Here is the scenarion and testcase:
1. Launch Java WebStart Application with extension as background
2. change the extension jar file to a new one.
3. Launch the same application - since the extension download is in the background same old jar will be used.
4. Lauch the same application - now it should take the new jar becs it is updated by step3. Action.

Here is the TestCase:
javaws -uninstall.
Step1: ssh jdeploy01.india.sun.com credentials - dtfadmin/ dtf123
cd /net/sqindia/export/disk13/jcg/javafx/workspace/webservices/tomcat/webapps/JavawsMustangIntegTest/update/jar
cp first_ext.jar extension.jar
Step1: Launch - http://jdeploy01.india.sun.com:8080/JavawsMustangIntegTest/update/jar_extension_background.jnlp
Title expected is "First Version" - it uses the first_ext.jar

Step2: Move to server
cp second_ext.jar extension.jar

Steps3:Launch the same app again.
Title expected is "First Version" - it is uses the firt_ext.jar while launchign bug in the background it should download the changed jar file
Now closed this.


Step4:Launch the same app again.
Now title expected is "Second Version" - Since the new extesion jar is downloaded in the background during Step3.

Here is the console logs for Step3:
