> Issue Type: Bug

> Affects Versions: 3.2

> 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.
