Re: Change logging level for Logger.throwing

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)
