FULL PRODUCT VERSION :
JDK 8u40

ADDITIONAL OS VERSION INFORMATION :
Windows 8.1 Enterprise

A DESCRIPTION OF THE PROBLEM :
Java webstart does not use the splash screen provided in the JNLP.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The downloaded splash screen is shown on subsequent runs
ACTUAL -
The default java splash is shown every time.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
I set the java to Trace log level and you can see it downloads the image

Then I went to the Java cache log:

cache\<#>\splash and open the splash.xml file

And found this: https\:/our.website.net/webstart/N-central/jrcc-1.6.jarjnlp=C\:\\Users\\<username>\\AppData\\LocalLow\\Sun\\Java\\Deployment\\cache\\<#>\\48\\782a1130-53d17b8b

Look the path after the = and browse to it in Windows Explorer. Open the file that matches the number at the end of the path with an image viewer and saw the correct splash.

So the image download works fine.

Then I went and run it again and saw this in the logs

cache: Resource https://our.website.net/images/webstart/jrccSplash.png has expired.
security: blacklist: hasBeenModifiedSince 1425480803934 (we have 1425477491411)
security: blacklist: hasBeenModifiedSince 1425480804181 (we have 1425477491411)
security: Certificate revocation enabled. Disable security validation optimizations.

At this point I am not sure why Java thinks the cache is expired because this exact JNLP used to work in Java 6.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
We have a custom application that runs through webstart.
