Accessing the class object in a static context

I often need to access the current class, for example for logging purposes:

public class Foo {
  private Logger logger = LoggerFactory.getLogger(getClass());

However, this won’t work in a static context, since you don’t have any this object to call getClass() on:

public class Foo {
  static private Logger logger = LoggerFactory.getLogger(Foo.class);

It’s always bothered me to have to copy/paste this line and then remember to replace the name of the class, so here is one way to make this snippet more generic:

public class ClassUtil extends SecurityManager {
  public static Class getCurrentClass() {
    return getClassContext()[1];

Which you use as follows:

public class Foo {
  private static Logger logger = LoggerFactory.getLogger(
      new ClassUtil().getCurrentClass());

A somewhat less hacky and cheaper approach is to instantiate an anonymous class in order to materialize a this object:

private static Class thisClass =
    new Object() { }.getClass().getEnclosingClass();
private static Logger logger = LoggerFactory.getLogger(thisClass);

Can you think of any other way?
