Windows 10
Oracle Java 8 version does not turn os.name property into Windows 7 when run in the compatibility mode
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run this code on Windows 10, running in compatibility mode
public class OSN {
public static void main(String args[]) {
System.out.println(System.getProperty("os.name"));
}
}
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Windows 7
ACTUAL -
Windows 10
REPRODUCIBILITY :
This bug can be reproduced always.
