/**
 * @deprecated This class was introduced to overcome the limitation that before 
 * Java 1.6, {@link IOException} did not have a constructor which took a 
 * {@link Throwable} argument. Since Pig code is now compiled with Java 1.6 and 
 * {@link EvalFunc} and {@link LoadFunc} user implementations should also use 
 * Java 1.6, they can use {@link IOException} instead. From Java 1.6, 
 * {@link IOException} has constructors which take a {@link Throwable}
 * argument.
