FULL PRODUCT VERSION :
8u60 b21 early access - 64-bit Windows JDK

ADDITIONAL OS VERSION INFORMATION :
Windows 8 (6.2.8400)

A DESCRIPTION OF THE PROBLEM :
We use the JavaFX native packager to produce native install bundles for Windows, Mac, and Linux versions of our product. We invoke the packager from an ant build script via the packager ant tasks. Our ant script and overall build process has not changed and continues to produce working bundles on 8u45 and earlier JDK releases. We create all of our Windows bundles from a 64-bit Windows 7 build machine. We use this Windows 7 build machine to produce both 64-bit and 32-bit Windows bundles (using a 64-bit JDK for the former and a 32-bit JDK for the latter, of course). While 8u60 continues to produce working 64-bit bundles for Windows 7, when the 8u60-generated native installer is run on Windows 8, the installer runs to completion, but the application fails to start, with the following stack trace (would attach a screenshot of the popup error dialog, but this form doesn't allow attachments):

REGRESSION.  Last worked in version 8u45

ADDITIONAL REGRESSION INFORMATION: 
In addition to the above problem, 8u60 also breaks 32-bit Windows XP support. Yes, I know that XP is no longer officially supported by Oracle, but it was working for our product just fine up to and including 8u45. I mention this in the hopes that both issues are somehow related and that a fix will allow us to continue to support our Windows XP customers, even if Oracle no longer supports that platform. 

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I can't easily bundle up our entire application and build but I will work with whoever looks at this bug to help him or her reproduce it.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
An unrelated rant: I used to have JavaFX JIRA access and the ability to submit bugs there. That has been productive for me and I believe for the JavaFX team, but that access has now been revoked apparently. I am now presented with an OpenJDK login screen, which doesn't take my credentials, and when I try the "forgot password" link it says an email has been sent yet the email never arrives.
