Hi everyone, I've had a lot of challenges with the latest Java 7_51 release because I run a java web start application and with all the security updates, I had to get a code signing certificate and sign the app just to even get it to run..

Now that I've done that part, I'm looking around at security permissions and noticing that I can no longer do things like copy to clipboard (I get AccessControlException) even with my signed app.

I have in my manifest.mf:
Permissions: sandbox

And in my jnlp
<security>
<all-permissions />
</security>

My question is, I would like to have the all-permissions I've been reading about in the manifest.mf which would let me do things like copy to clipboard, but as soon as I put Permissions: all-permissions in the manifest file, the java web start application will be denied to launch even though it is a trusted signed app..

Please help if you can!
