FULL PRODUCT VERSION :
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) Client VM (build 24.65-b04, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [version 6.3.9600]
Windows 8.1 32 bits

A DESCRIPTION OF THE PROBLEM :
System.getProperty("os.name") will report "Windows 8" when run using a launcher that load jvm.dll to start a JVM whereas running the same code using java.exe will report "Windows 8.1".

Only one JVM is installed and it's the latest version of Java 7 (update 67).
This version includes the fix for bug JDK-8022452 ("Hotspot needs to know about Windows 8.1 and Windows Server 2012 R2").

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- Run the attached Java code using java.exe: output will be Windows 8.1
- Build the launcher exe file (done with Visual Studio 2013 Express) and run the same class: output will be Windows 8. To run this test you need in a terminal to type: TestJvm.exe ShowOsName C:\path\to\class\file\folder

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When running the class using the custom launcher that use jvm.dll I expected the output of os.name to be the same as when running with java.exe: Windows 8.1
ACTUAL -
os.name: Windows 8

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
I found out about this issue running Eclipse that use by default jvm.dll.
Specifying -vm argument in eclipse.ini configuration file and provide full path to javaw.exe allow to bypass this bug.
