ppkarwasz opened a new pull request, #789:
URL: https://github.com/apache/commons-io/pull/789

   This change makes `AbstractOrigin` implement `Closeable` and updates the 
Javadoc of all “getter” methods that return `Closeable` resources. The Javadoc 
now explicitly warns that:
   
   * Closing the returned resource will also close the underlying 
`AbstractOrigin`.
   * Ownership of the underlying resource is transferred to the caller.
   
   ### Rationale
   
   * Callers must always close the returned resource. Some implementations 
create a new resource on each call, which must be released explicitly.
   * Other implementations return the underlying origin directly, making it 
impossible to guarantee a close-shielded wrapper.
   * The primary usage of `AbstractOrigin` is within `AbstractStreamBuilder`, 
whose implementations typically wrap closeable resources.
   
   Before you push a pull request, review this list:
   
   - [x] Read the [contribution guidelines](CONTRIBUTING.md) for this project.
   - [x] Read the [ASF Generative Tooling 
Guidance](https://www.apache.org/legal/generative-tooling.html) if you use 
Artificial Intelligence (AI).
   - [x] I used AI to generate the Javadoc.
   - [x] Run a successful build using the default 
[Maven](https://maven.apache.org/) goal with `mvn`; that's `mvn` on the command 
line by itself.
   - [x] Write unit tests that match behavioral changes, where the tests fail 
if the changes to the runtime are not applied. This may not always be possible, 
but it is a best-practice.
   - [x] Write a pull request description that is detailed enough to understand 
what the pull request does, how, and why.
   - [x] Each commit in the pull request should have a meaningful subject line 
and body. Note that a maintainer may squash commits during the merge process.
