I'm writing mobile phone apps and don't usually have stack of line information.
When I get an NPE like this and have situation you describe it usually turns
out I have
a null table. There may not be too many other options although I guess depending
on the parameters you could be passing a null but this could throw illegal arg
depending
on how used etc. Note sure now if HAshtable.get(null) throws IllegalArg or not.
