pjfanning opened a new pull request, #3716: URL: https://github.com/apache/pekko/pull/3716
### Motivation The Java stream quickstart sample copies each tweet's hashtag `Set` into a new `ArrayList` before returning it from `mapConcat`. The Java DSL `mapConcat` accepts any `java.lang.Iterable`, so the copy is unnecessary and suggests to readers that a `List` is required. ### Modification Return `t.hashtags()` directly in the `#hashtags-mapConcat` and `#graph-dsl-broadcast` snippets of `TwitterStreamQuickstartDocTest`, and remove the unused `ArrayList` import. ### Result The Java sample shown in the stream quickstart matches the documented contract that the function returns an `Iterable`. ### Tests - Not run - docs only ### References None - docs sample cleanup -- This is an automated message from the Apache Git Service.
