When debugging a very simple IMlet(source codes below), after hitting CTRL+F5, org.openide.util.RequestProcessor$SlowItem exception occurred.
Please refer to attached NetBeans log(messages.log)

Sample IMlet source codes:

package jmeelogging;
import com.oracle.util.logging.*;
import javax.microedition.midlet.*;
public class IMlet extends MIDlet {
    Logger logger = Logger.getGlobal();
    public void startApp() {
        logger.addHandler(new MyHandler());
        logger.setLevel(Level.INFO);
        logger.log(Level.INFO, "A message of Level.INFO.");      // Will be printed out in console.
        logger.log(Level.FINEST, "A message of Level.FINEST.");  // Will NOT be printed out.
        logger.log(Level.SEVERE, "A message of Level.SEVERE.");  // will be printed out in console.
        destroyApp(true);
        notifyDestroyed();
    }
    
    public void pauseApp() {
    }
    public void destroyApp(boolean unconditional) {
    }
    class MyHandler extends Handler {
        public void publish(LogRecord record) {
            System.out.println(record.getMessage());
       	}
       	public void flush() {
      	}
       	public void close() {
       	}
    }
}
