In 6u12 b02, there are several issues in Plugin/Webstart JRE dialogs in the Control Panel.

1. You may see duplicate JRE entries in the dialog. In 6u10, jre entries from Windows registry are mistakenly set "registered" property to false. While we are fixing the issue in 6u12 b02, it causes both registered and unregistered entries to show in the java control panel.

2. Installed JREs (from windows registry) are always enabled. This is because when we try to correct the "registered" property issue, the "enabled" property got overridden in the deployment.properties.

This CR will be fixed in 603.
In addition, there is a testing CR 6781143 related to b02 changes. When we dump user jre information to the deployment.properties, we need compact the indices. So index starts from zero and increments by one
