A DESCRIPTION OF THE REQUEST :
Position throws an IllegalArgumentException if the new position is > limit or < 0 but doesn't state what the new position is. The exception should contain the position in error in its message string.

JUSTIFICATION :
It is hard to debug position related bugs without this change.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
an IllegalArgumentException with a message like:

String.format("New position is %d, but cannot be > %d or < 0", newPosition, limit)
ACTUAL -
An IllegalArgumentException with no message at all.
