Perhaps this method should be overridden in LibraryElement.

Done.

+      LibraryElement library = this;
+      return library.entryCompilationUnit;
+    }
     Element element = this;
-    while (element !== null && !element.isCompilationUnit()) {

This will ensure a null error if something is setup incorrectly. I like that.

       element = element.enclosingElement;
     }
     return element;
