> On an invalid logger name like e.g. '.logger1', log4cxx loops forever when trying to update parents in the logger hierarchy.
> The reason might be that in that special case
> i = name.find_last_of(0x2E /* '.' */, i-1)
> returns 0, and in the next iteration find_last_of starts over again from string::npos.
