> I try to use the CharArraySet for a filter I am writing. I heavily use char-arrays in
my code to speed up things. I stumbled upon a bug in CharArraySet while doing that.
> The method _public boolean contains(char[] text, int off, int len)_ seems not to work.
> When I do 
> {code}
> if (set.contains(buffer,offset,length) {
>   ...
> }
> {code}
> my code fails.
> But when I do
> {code}
> if (set.contains(new String(buffer,offset,length)) {
>    ...
> }
> {code}
> everything works as expected.
> Both variants should behave the same. I attach a small piece of code to show the problem.
