jars no longer seem to be signed. JARSigningException: Found unsigned entry

Question

NB 7.4RC2, Win 7

In Java Control Panel, the "Keep Temporary Internet Files" checkbox is checked.

I am signing my Web Start application with trusted certificates. However, the 3rd party jars in dist/lib seem to be unsigned.

C:\Program Files (x86)\Java\jdk1.7.0_40\bin\jarsigner" -verify javafx-dialogs-0.0.3.jar

jar is unsigned. (signatures missing or not parsable)

So when I run my application in the debugger, it refuses to start complaining of unsigned jars

ExitException[ 3]com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: file:/C:/Users/me/Documents/NetBeansProjects/MyApp/dist/lib/RXTXcomm.jar

I get the same error when I run with self signed jars, “Found unsigned entry in resource”. It is as if NetBeans stopped signing the jars.

I deleted all temporary files in the Java cache from Java Control Panel. Now it fails to run clicking both Run and Debug in the IDE, and also copying the dist folder to the desktop and clicking the jnlp file.

ExitException[ 3]com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: file:/C:/Users/me/Desktop/dist/lib/RXTXcomm.jar

while building:

........

security: Trust for: file:/C:/Users/me/Documents/NetBeansProjects/MyApp/dist/lib/RXTXcomm.jar has ended: Wed Dec 31 18:00:00 CST 1969

Does anyone know what is causing this?

Update: In NetBeans, I selected Project Properties and under Run, selected Run As “default configuration”. Earlier, Run As “WebStart” was selected. Now it starts normally. Was it a NetBeans bug or a feature?
