using getMethods() on interfaces allows you to see the static initializer for the interface if it has one. here's a test case.

import java.lang.reflect.*;

interface i {
    // cause the interface to have a static initializer
    Object o = new Object();
}

public class r {
    public static void main(String[] args) throws Exception {
Method[] methods = Class.forName("i").getMethods();
for (int i = 0; i < methods.length; i++) {
if (methods[i].getName().equals("<clinit>"))
throw new InternalError("shouldn't see clinit");
}

    }
}
