Manfred,

I am not following. Transient references are not serialized. So by
construction, after serialization they are null. Would it be possible
for you to supply a test case showing how code relying on SLF4J
loggers fails while code relying on JCL loggers would not? 

The following code may be start:

package org.slf4j;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

import junit.framework.TestCase;

public class SerializationTest extends TestCase {


  public void testSmoke() throws Exception {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(baos);
    Logger logger = LoggerFactory.getLogger("x");
    Apple apple = new Apple();
    apple.setLogger(logger);
    oos.writeObject(apple); 
    ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
    ObjectInputStream ois = new ObjectInputStream(bais);

    Apple apple2= (Apple) ois.readObject();
  }
}


package org.slf4j;

import java.io.Serializable;

public class Apple implements Serializable {
  private static final long serialVersionUID = 1L;

  transient Logger logger;

  void setLogger(Logger logger) {
    this.logger = logger;
  }

  void doIt() {
    logger.debug("hello");
  }
}
