Most of the places where we produce warnings, or where we provide verbose output, are done by printing. At a minimum, those should go to `System.err` rather than `System.out`. Unless there is an API whose expected result is to print something to `System.out`, a library really shouldn't print to System.out (as opposed to a test or a demo app, where it's fine). So the only places I would expect to see it in the library -- meaning source code under `modules/javafx.*/src/main/java/` -- would be in examples in javadoc comments. We could file a second follow-up issue (RFE) to consider changing some of our print statements to use logging. ------------- PR: https://git.openjdk.org/jfx/pull/1025
