Change logging level for Logger.throwing

[Stefan Istrate]

Is there any possibility to change the logging level used by
Logger.throwing from FINER to SEVERE?

Thanks,
Stefan

It would be quite straightforward for you to write a method that
create the same LogRecord that thrown() does except that the level is
set to SEVERE, and then log it.

Not really.

The FINER is hard coded in that method.

If you need a practical solution and are willing to
do what it takes to solve the problem, then you
can use AspectJ.

Just compile all your code together with the
following:

import java.lang.reflect.*;
import java.util.logging.*;

import org.aspectj.lang.*;
import org.aspectj.lang.annotation.*;

@Aspect
public class Hack {
@Pointcut("call(void
java.util.logging.Logger.throwing(String,String,Throwable))")
public void changeLevel() {}
@Around(value = "changeLevel()")
public void makeSevere(ProceedingJoinPoint pjp) {
Logger log = (Logger)pjp.getTarget();
Object[] args = pjp.getArgs();
LogRecord lr = new LogRecord(Level.SEVERE, "THROW");
lr.setSourceClassName((String)args[0]);
lr.setSourceMethodName((String)args[1]);
lr.setThrown((Throwable)args[2]);
log.log(lr);
}
}

and the resulting code will do what you want:

C:\>javac TLog.java

C:\>java TLog
11-04-2009 22:34:25 TLog main
FINER: THROW
java.lang.Exception: Ooops
at TLog.main(TLog.java:9)

C:\>ajc -source 1.5 TLog.java Hack.aj

C:\>java TLog
11-04-2009 22:34:35 TLog main
SEVERE: THROW
java.lang.Exception: Ooops
at TLog.main(TLog.java:9)
