Log4j2 false positive

When using the Log4j2 API java:S2275 triggers a false positive if the last argument is a Throwable.

Example:

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
...
  private static final Logger LOGGER = LogManager.getLogger(MyClass.class);
...
String param1 = "hello";
String param2 = "world";
Throwable param3 = new RuntimeException();
LOGGER.info("This is a comment with {} {} {} three parameters.", param1, param2, param3);

SonarQube Version 8.3.1 (build 34397)
