    Description

      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

      if (set.contains(buffer,offset,length) {
        ...
      }
      

      my code fails.

      But when I do

      if (set.contains(new String(buffer,offset,length)) {
         ...
      }
      

      everything works as expected.

      Both variants should behave the same. I attach a small piece of code to show the problem.
