B4J Question warning when opening a com port in jserial

[HansDieter]

I try to connect my Uno with a USB port via a virtuelle serial port. It seems to work but there is a red warning in the logs:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

The warning happens when sp.ListPorts works.

You can ignore it.

If these warnings really annoy you, there is a way to remove them.
