## Reproduction
The code below used to run fine, then after upgrading to 2.24.2 it started
throwing on application startup. Getting rid of the `LOGGER` variable "fixes"
the problem.
```
import org.apache.logging.log4j.core.LogEvent;
import org.apache.logging.log4j.core.config.plugins.Plugin;
import org.apache.logging.log4j.core.lookup.StrLookup;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@Plugin(name = "MyPlugin", category = StrLookup.CATEGORY)
public class MyPlugin implements StrLookup {
private static final Logger LOGGER =
LoggerFactory.getLogger(MyPlugin.class);
static {
LOGGER.info("Log stuff");
}
@Override
public String lookup(String key) {
return "";
}
@Override
public String lookup(LogEvent event, String key) {
return "";
}
}
```
