JAR resources in JNLP file are not signed by same certificate, but they are

I just recived a new signing certificate from Thawte and need to sign my jar files.
First I strip the old certificate META-INF\*.RSA, META-INF\*.SF & META-INF\*.MF from every jar file.
Then I resign every jar file with the new certificate and uploads them to the server.

Now, when I run my application I get: "Unable to launch" and the error: "#### Java Web Start Error: #### JAR resources in JNLP file are not signed by same certificate".

If I press OK, and try to run my application once more the error is gone and I get the the standard "Security Information" optionpane with the message "The application's digital signature has been verified..." and if I press "Run" the application starts normally

I test on a Virtual Windows XP inside Windows 7 with Java 7 Update 5 and my Windows 7. Jarfiles are signed with Java 6 update 33.

Why do I get the first "Unable to launch" when it works the second time?
