The meaning of the java.vendor property?

I was wondering if it’s OK to modify the “java.vendor” system property as reported by System.getProperty() in our OpenJDK builds. Some binary OpenJDK distribution builders seem to be doing so, but others not. Is there a rule for this? The documentation does not seem exactly conclusive:

What is a “vendor” in this context? Is it always supposed to be “Oracle Corporation” to stay compatible? Or is it supposed to be whoever builds and packages the binaries so we can track the origin of the binary artifacts better?
