Yes. Your plugin class must implement the IStartup interface and its method
(earlyStartup()), as well as defining the extension point in your
plugin.xml. I suspect that you have defined the extension point but not
implemented the interface (thus the ClassCast)?

I have implemented the interface:

package ...;

import org.eclipse.core.runtime.IPluginDescriptor;
import org.eclipse.ui.plugin.AbstractUIPlugin;
import org.eclipse.ui.IStartup;

/public class MyPlugin extends AbstractUIPlugin implements IStartup{

public MyPlugin(IPluginDescriptor descriptor) {
super(descriptor);
}

public void earlyStartup()
{
//System.out.println("earlyStartup");
}

}

The stack trace shows you are using the DefaultPlugin. This means you
are missing the "class" attribute for your plugin definition.
