bug: Qualified type references in catch clauses resolved incorrectly (noclasspath)

[slarse]

I have a problem in noclasspath mode where a qualified type reference in catch clauses are resolved incorrectly. Take the following code snippet.

public class CatchQualifiedReference {
    public static void main(String[] args) {
        try {
        } catch (some.neat.pkg.CustomException e) {
        }
    }
}

In noclasspath mode, some.neat.pkg.CustomException becomes a type references with the qualified name some. Which is pretty wild. The problem appears to be that TypeBinding.readableName() actually returns just some here:

spoon/src/main/java/spoon/support/compiler/jdt/ReferenceBuilder.java

Line 961 in 3a8d04d

char[] readableName = binding.readableName();

So this could be a problem with the JDT library rather than with Spoon. I'm not certain. I'll put up a PR with a test case, but I haven't had the time to look into a solution.
