tidy warning: anchor already defined

Above tidy warning seen when the class name and a method name have same name and differ in uppercase/lowercase.

Sample test case:
import java.io.*;
public class Baz {
    /**
     * Baz doc.
     *
     * @throws EOFException
     */
    public void baz() throws IOException {
    }
}

javadoc generates a constructor anchor as: <a name="Baz--">
and a method anchor as: <a name="baz--">

tidy reports error for such cases.
Based on discussion with dev, anchors names generated for constructor will have to be prefixed with some text to differentiate such cases.

UPDATE: As suggested by Jon, above tidy error is also seen for cases when a class has equivalent methods like abc() and ABC(), so looks like the error is not related to anchor names for constructors.
