Yes, I did, but not within Spark, but outside, in REPL. As a matter of fact, [Properties.javaClassPath](https://github.com/scala/scala/blob/2.12.x/src/library/scala/util/Properties.scala#L126) ends up calling [System.getProperty(name, alt)](https://github.com/scala/scala/blob/2.12.x/src/library/scala/util/Properties.scala#L52) so the change is truly a refactoring (to ease reading the class later on).
