I have to say that our JNLP have the libraries referened as this:

 <jar href="spring-aop.jar" version="2.5.5"/>

This way the application was running well until Java8u66.

I was doing some tests and I realized that the application works fine if i change the way we reference the libraries in my jnlp file, like this:

 <jar href="spring-aop-2.5.5.jar"/>

But this not a good solution for us due to lateral effects (more traffic in starting application).

REGRESSION. Last worked in version 8u72

ADDITIONAL REGRESSION INFORMATION:
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b18)
Java HotSpot(TM) Client VM (build 25.66-b18, mixed mode)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- Make a JNLP File referencing jar libraries with the tag "version". Ensure the libraries ar all signed.
- Try to start the application

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A Window with error that says that the certificate can't be validated
ACTUAL -
The same

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Not using the tag "version" when referencing libraries in the jnlp file.
