/**
* There are six methods in java.lang.Long which transform strings
* into a long or Long value:
*
* public Long(String s)
* public static Long decode(String nm)
* public static long parseLong(String s, int radix)
* public static long parseLong(String s)
* public static Long valueOf(String s, int radix)
* public static Long valueOf(String s)
*
* Besides decode, all the methods and constructor call down into
* parseLong(String, int) to do the actual work. Therefore, the
* behavior of parseLong(String, int) will be tested here.
