recently I have upgraded to jre 1..7.45b18 and started getting the security popup saying Do you want to run this application Publisher: UNKNOWN Running applications by UNKNOWN publishers will be blocked in a future release because it is potentially unsafe and a security risk.

My jar files are self-signed using 'signjar' ant utility, can someone advice how to stop this popup from appearing. I understand something needs to be changed the way jars are signed and the java web start to recognize it.

this is due to the security restrictions coming from Oracle. See Oracle Security Dialogs:

If the application is self-signed or signed by an unknown authority, the publisher is shown as UNKNOWN.
