Jochen Wiedmann resolved COLLECTIONS-323.
-----------------------------------------
Resolution: Fixed
Fix Version/s: (was: 4.x)
3.2.2
Assignee: Jochen Wiedmann
Applied for all classes mentioned by Hen, except for LRUMap, In the case of
LRUMap, this would mean to silently increase the capacity, which is most likely
not what the user would expect.
> Behavior of constructors CaseInsensitiveMap inconsistent with standard Java

> Environment: Any
> Reporter: Maarten Brak

> The constructor CaseInsensitiveMap(int initialCapacity) throws an
> IllegalArgumentException if "the initial capacity is less than one". This is
> inconsistent with the standard Java HashMap constructor HashMap(int
> initialCapacity), which throws an if IllegalArgumentException if "the initial
> capacity is negative".
> Thus:
> new HashMap(0) ==> no exception
> new CaseInsensitiveMap(0) ==> IllegalArgumentException.
> This inconsistency is confusing.
> Actions:
> - Change Javadoc (this shouldn't be a problem in practice since surely there
> is no code around depending on the fact that the constructor throws an
> IllegalArgumentException :-))
> - Change code.
