BindGen does not work on classes in the default package

Trying to run the binding generator on a class in the default package (i.e. no package name) strips the first letter from the class name and fails.
The bug seems to b in the GlobalCustom class (split + 1).

private ClassCustom buildClassCustomization(String type) {
int split = type.lastIndexOf('.');
if (split < 0)

PackageCustom pack = getPackage(type.substring(0, split));
ClassCustom clas = pack.addClassCustomization(type.substring(split + 1));
return clas;
}
