Perhaps but that seems better than allowing the JVM to write to a file owned by the application just because it happened to close System.out. This could certainly explain some weird file corruption bugs we have seen over the years. And with enough randomness, combined with not normally closing System.out/err that we have not recognized it for the problem that it is.
