A DESCRIPTION OF THE REQUEST :
In class AbstractList, the two Iterators discard IndexOutOfBoundsExceptions in next(), remove(), previous() and set(). These methods just throw a new exception, which does not contain the cause.

JUSTIFICATION :
This behaviour makes it difficult to locate errors that occour in derived classes.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The cause of the exception should be included in the thrown exception.
