FULL PRODUCT VERSION :
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b25)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux CHI-RENGELS-01 3.13.0-47-lowlatency #78-Ubuntu SMP PREEMPT Tue Mar 3 17:53:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
After downloading a single large application (> 200 MB), the application viewer is so slow it is unusable. It takes minutes to display the initial table, and minutes to switch between the 'applications' and 'resources' tab.

You can run/download a similar app:

https://www.theice.com/launch

and see similar behavior (although it is not quite as slow, I believe since it is only 50 MB and have halve as many jars.




ADDITIONAL REGRESSION INFORMATION:
I get similar behavior with 1.7.0_67

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Install a large JNLP webstart application. Use javws -viewer.

ACTUAL -
You can see in the stack-trace that during table display it is continually re-writing all of the jars in saveUpgrade(), called by readIndexFile().

This happens EVERY load, and screen switch. Clearly something is not being marked/saved correctly, and it is continually saving...

ERROR MESSAGES/STACK TRACES THAT OCCUR :
I did a stack-dump, and the AWT is busy doing:
