Missing TypeDeclaration name in gen.jdt

[FlorianLehmann]

Hi,
I recently found an issue in the JDT generator.

The two files : Left.java and Right.java are considered equivalent, but they aren't.

Left.java :

     public interface Main { }

Right.java :

     public class Main { }

It is possible to observe this issue with the code below :

        File left = new File("src/main/resources/Left.java");
        File right = new File("src/main/resources/Right.java");

        TreeContext leftTree = new JdtTreeGenerator().generateFromFile(left);
        TreeContext rightTree = new JdtTreeGenerator().generateFromFile(right);
        Matcher m = Matchers.getInstance().getMatcher(leftTree.getRoot(), rightTree.getRoot());
        m.match();

        ActionGenerator g = new ActionGenerator(leftTree.getRoot(), rightTree.getRoot(), m.getMappings());
        List<Action> actions = g.generate();

        System.out.println("actions.size() : " + actions.size());

actions.size() : 0

This issue seems to be related to missing TypeDeclaration name in gen.jdt.

Thanks!
