Classloader problem

[Maksimenko Alexander]

Hi!
I try to describe my problem. I have to use instance of 
org.apache.commons.logging.Log in my components instead of Logger. So 
I've created my implementation of 
org.apache.avalon.logging.provider.LoggingManager. This implementation 
instantiates another LoggingManager implementation and wraps produced 
Logger instance. My wrapper implements both Logger and Log interfaces:

public class LogLogger implements Log, Logger{
  protected Logger logger = null;
  public LogLogger(Logger logger) {
    this.logger = logger;
  }
  public boolean isTraceEnabled() {
    return logger.isDebugEnabled();
  }
  public boolean isDebugEnabled() {
    return logger.isDebugEnabled();
  }
.....
}
So I can cast it to Log in my component:
  Log myLogger;
  public void enableLogging(Logger logger) {
    myLogger = (Log)logger;
  }
But unfortunately a get the following exception:

java.lang.ClassCastException
net.softwarium.commons.logger.avalon.TestComponent.enableLogging(TestComponent.java:47)
org.apache.avalon.activation.appliance.impl.DefaultAppliance.applyLogger(DefaultAppliance.java:545)
I discoved the cause of the exception is that Log class for 
LoggingManager and Log class for Component lay in distinct classloaders:

LoggingManager ClassLoader --->  Log ClassLoader ---> Merlin Impl 
ClassLoader --->.....
MyComponent ClassLoader ---> LogClassLoader ---> Merlin Impl ClassLoader 
--> ....

but I can't imagine how I can reapir this situation :(
