-------------------------------------

I am pretty sure you are right - here is a chance to contribute to the project. Conisder writing a unit test that demonstrates the problem and *fails*. Then fix the issue and show that the test succeeds. Once done, publish a pull request.

> in org.apache.sshd.common.file.util.ImmutableList.subList() the if criteria is wrong:
> wrong code:
>     @Override
>     public ImmutableList<T> subList(int fromIndex, int toIndex) {
>         if (fromIndex == from && toIndex == to) {
>             return this;
>         }
>         return new ImmutableList<>(data, from + fromIndex, from + toIndex);
>     }
> should be:
>     @Override
>     public ImmutableList<T> subList(int fromIndex, int toIndex) {
>         if (fromIndex == 0 && from+toIndex == to) {
>             return this;
>         }
>         return new ImmutableList<>(data, from + fromIndex, from + toIndex);
>     }
