Java's system properties returning "Windows 8.1" after upgrade to "Windows 10"

Question

My upgrade to Windows 10 went very well and only needing a few programs reinstalled. Java was one of those because Eclipse did not start anymore: eclipse 64 bit didn't run but 32 bit did and I am on a 64 bit machine where it used to work. This was easily fixed by uninstalling and reinstalling Java and the JDK. However, one issue still remains.

System.getProperty(" ... ") returns next wrong values:

• "os.name" = "Windows 8.1" should say "Windows 10"
• "os.version" = "6.3" is this wrong also?

Is this a problem with Java or is this because Windows 10 was done through a system-update and my system is technically still "Windows 8.1"?

Answer 1

It's a problem with current Java.

MS changed some API behavior in Windows 10 and Java doesn't recognise it correctly. See https://bugs.openjdk.java.net/browse/JDK-8059803 for details.

This will be fixed in upcoming jdk8u60. Latest dev version reports next on Windows 10:

os.name = Windows 10
os.version = 10.0
