> Hot on the heals of #29288, this PR replaces `ArrayDeque` with `ArrayList` for the Inflater cache implementation in `ZipFile.CleanableResource`.
>
> With this PR, we change the order of the cache from a LIFO queue to a FIFO stack backed by ArrayList. The order seems unimportant, and has indeed been FIFO in the past when using `java.util.Vector`. Intuitively, it should be better to return the most recently used Inflater.
>
> No tests updated, strict refactoring, `noreg-cleanup`.
