> While tracing some TestBlobHandler failures with the thai locale I found that 
> the problem was MessageFormat.format which when given a Number ultimately 
> executes NumberFormat.getInstance(getLocale()).format(argument). In thai 
> locale, this transforms the digit 1 to a thai character and hence fails the 
> test.
> We should audit all usages of MessageFormat.format to see if any Number 
> objects are being passed as argument and wrap them with String.valueOf().
> I don't think forbidden-api can catch such problems. Perhaps we just forbid 
> MessageFormat.format itself?
