How to get rid of them?

According to the source code of the class GuavaDeprecation it should be possible to change the log level of such messages to eg. "DEBUG", using a system property (see eg. https://github.com/apache/jackrabbit-oak/blob/1.22/oak-core/src/main/java/org/apache/jackrabbit/oak/core/GuavaDeprecation.java😞
private static final String TLOGLEVEL = System.getProperty(GuavaDeprecation.class + ".LOGLEVEL", DEFAULT);
and then ignore them with setting higher level in the logger configuration. However, adding a runtime parameters to the java command has not helped:
-D"class org.apache.jackrabbit.oak.core.GuavaDeprecation.LOGLEVEL=debug"
AEM version is 6.5.17.0.
