To keep the original exception.

it is about how an exception is related to another ...
let us say ... you get an exception say SQLException which happened due to some sql related confusion but in actual it is a I/O Exception ...
so the two exceptions are chained together ...

JavaRanch Style Guide
subject: exception chaining
NX: concerning exception handling
cushioning exception from bottom up...
