The problem is:
1, logging is referenced and used before `PropsUtil` is initialized
2, we can't change wrappers because they are saved in `private static final Log _log =...` variables

An option here is to wrap the `log` again :)

OK, I try to go this way, now `setLogFactory()` should be:

	for (Map.Entry<String, LogWrapper> entry : _logWrappers.entrySet()) {
		String name = entry.getKey();
		LogWrapper logWrapper = entry.getValue();

        if (_SECURE_LOGGING_SANITIZE_ENABLED) {
			logWrapper.setLog(new SecureLogWrapper(logFactory.getLog(name)));
        }
        else {
			logWrapper.setLog(logFactory.getLog(name));
        }
    }
