----------------------------------------------------------------
Still not clear to me how this will impact real-world scenarios, but I guess
every little bit helps.
I fixed some bugs around the remove() operations of the immutable list, since
they always didn't throw UnsupportedOperationException (seems like a design
issue with AbstractCollection). Is is possible that the immutable map has
similar issues, but I didn't look into it since it wasn't causing any CT
failures.
Please close if you are satisfied.

> The unmodifiable collection wrappers are .. wrappers and as such add a
> slight overhead.
> In the case of felix, the resolution process does use a lot of those maps for
> bundle capabilities and requirements and the overhead tends to become non
> negligible.
