General:

-        Modify log4j extension bundle to support SMTPAppender.

The modified JAR does not work here in "standard" Java application (i.e. no OSGi or Eclipse framework). 

Running this class:

public class LogTester {
    public static void main(final String[] args) {
      org.apache.log4j.Logger.getLogger("test");
    }
}

results in:

It seems that your modification of the MANIFEST.MF is considered evil by the JDK class loader (-;

Can you fix this?
