mini project with problematic inter-type constructor declaration

i have an aspect with an inter-type declaration, which looks like this:

package de.wieger.sample;

public aspect Person_ITD {
    public Person.new() {
        this();
        // intentionally left blank
    }
}


When i invoke "Organize Imports" in eclipse, i get the following error:
"Compilation unit has parse errors: Constructor call must be the first statement in a constructor".

From my prospective, it seems like the method AjOrganizeImportsOperation#collectReferences is a little bit too strict about what should be considered as a relevant parsing error.

I have seen, that AjCompilationUnitProblemFinder#isARealProblem filters out a lot of problems like the one causing trouble when invoking "organize imports". The method conains an explicit snippet, dealing with the problematic syntactic construct:

if (numArgs == 0 && id == IProblem.InvalidExplicitConstructorCall) {
    // ITD constructor making explicit this() call.
    // lots of potential for false negatives
    return false;
}

Maybe this could indicate the direction for a fix?

I have attached an archive with a mini project containing the source code, which demonstrates the problem when invoking "organize imports" on the inter-type declaration.
