Weird value of System.getProperty("os.name")

Im trying to get the System.getProperty("os.name") of my own Windows 7 machine. I am running a java application directly from the machine from within Eclipse.

The returned value is "windows vista"!

Seems wrong, very wrong. And yes I am sure that I am running the app on a windows 7 machine...

Any idea as to what i开发者_开发百科s going on here?

This is a known bug: Bug ID 6819886. It mentions that it's been fixed in among others Java 7(b55) and Java 6u14(b04). So upgrading to the latest should resolve the issue.
