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.

That doesn't mean you can't configure JDK logging as well. If not for 
anything else, just to silence PlatformLogger output.

Alternatively, you can have PlatformLogger output through Log4J. Use 
jul-to-slf4j bridge and slf4j-Log4J backend.

See here:

http://www.slf4j.org/legacy.html#jul-to-slf4j

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);
