Incorrect warning that the application does not have a Permissions attribute

FULL PRODUCT VERSION :
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux garfield 3.8.0-33-generic #48-Ubuntu SMP Wed Oct 23 09:16:58 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux


A DESCRIPTION OF THE PROBLEM :
Whenever I try to launch a signed application via webstart, I get a warning saying that the Permissions attribute is missing from the manifest. However the manifest file does contain the required Permissions attribute.

I have determined that this error is related to the use of the JNLP servlet with versioning. I am using the same JNLP servlet distributed with JDK 1.7u51 The versioning information is important in our setup.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Produce signed jar file with Permissions, Codebase and other attributes in Manifest file.
Launch jar via JNLP, using the JNLP servlet with version information.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Application runs without warnings.
ACTUAL -
Dialog with yellow warning is displayed

ERROR MESSAGES/STACK TRACES THAT OCCUR :
This application will be blocked in a future Java security update because the JAR file manifest does not contain the Permissions attribute. Please contact the Publisher for more information. More Information

REPRODUCIBILITY :
This bug can be reproduced always.
