Java Web Start Security warning JNLP. Bug in JWS? 7u51

We are using java web start to launch a GUI java program. We sign all the jars including third party jars. We also added the Permissions: all-permissions attribute to the manifest of all our jars, but not to the third party jars.

In java 7u51 we still get the warning that 'this application will be blocked'.

I have tried looking through the java console logs after starting web start with -verbose but didn't see anything that helped me resolve this.
