FULL PRODUCT VERSION :
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b18, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 10.0.10586]
Linux 3.12.11-201.fc19.i686 #1 SMP Fri Feb 14 19:35:05 UTC 2014 i686 i686 i386 GNU/Linux
A DESCRIPTION OF THE PROBLEM :
The built-in parser of the JavaScript Date() object in the JavaFX webview component returns a wrong date if used with a date after February 28 2034.
Example:
new Date('February 28, 2034 10:00:00').toUTCString() --> Tue, 28 Feb 2034 10:00:00 GMT (correct)
new Date('March 1, 2034 10:00:00').toUTCString() --> Tue, 28 Feb 2034 10:00:00 GMT (incorrect)
For all dates after February 28 2034, one day is missing.
It works properly if the Date() constructor with the components is used:
new Date(2034, 1, 28, 10, 0, 0).toUTCString() --> Tue, 28 Feb 2034 10:00:00 GMT (correct)
new Date(2034, 2, 1, 10, 0, 0).toUTCString() --> Wed, 01 Mar 2034 10:00:00 GMT (correct)
This bug is applicable in both Windows and Linux, both x86 and x64 versions of the JRE.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached web page within a JavaFX WebView.
REPRODUCIBILITY :
This bug can be reproduced always.
