Hi,

I'd like to use one of the Bindings.select* methods but can't really accept the tons of stderr output it generates for null steps. According to this ticket...

[#RT-35957] Bindings class spits out a lot of unneeded log messages
https://javafx-jira.kenai.com/browse/RT-35957

... 8u20 resolves this by logging on the FINE level. But how can I suppress this output then? As far as I know the platform logger logs to stderr if JDK logging is not used - and we are on log4j. Which means I get FINE logging on stderr which does not help much.

Can you use the platform logger API? Like the following:

        sun.util.logging.PlatformLogger
            .getLogger("bla.bla")
.setLevel(sun.util.logging.PlatformLogger.Level.WARNING);
