How do they perform their logging? Do they use some logging library?
If yes, then you should configure that library.

swallowOutput works for simple things like System.out.println(), but
it fails in certain more complex cases
E.g., java.util.logging.ConsoleHandler (see your logging.properties)
is created at some early time when the server starts. It remembers a
reference to the original System.out (err) stream and thus is not
affected by swallowOutput.
Note the following line in logging.properties:
.handlers = 1catalina.org.apache.juli.FileHandler,
java.util.logging.ConsoleHandler
It means that if some event is not logged by other handlers, by
default it will be logged both by 1st FileHandler and by
ConsoleHandler. If you remove ConsoleHandler from that line those
events won't be printed to the console (and thus to the catalina.out)
