openjfx-dev Digest, Vol 34, Issue 36

[Daniel Fuchs]

Hi,

I don't recommend using sun.* proprietary APIs.
The safest way to suppress the logger output would be to
switch it off in a logging.properties file.

-Djava.util.logging.config.file=<logging.properties>

and inside:

<logger-name>.level = OFF

best regards,
