⚡ Key issues to review

Code Consistency
The refactoring introduces a consistent use of `LOGGER` instead of multiple logger instances which is a good practice. However, ensure that the `LOGGER` is appropriately configured elsewhere in the codebase to handle the logging as expected. Exception Handling
The new exception handling with logging in the `read` and `readAsync` methods improves clarity and maintainability. However, returning `null` in case of exceptions (lines 450, 461) could lead to `NullPointerExceptions` elsewhere. Consider handling these cases more robustly. Method Visibility
Several methods have been changed to private, which is good for encapsulation. However, ensure that these changes do not affect any subclasses or tests that might be relying on these methods being accessible.

PR Code Suggestions ✨

Category	Suggestion	Score
Best practice	Ensure resources are closed properly by adding a finally block ___ Consider adding a finally block to ensure that resources are closed in case of exceptions during XML stream processing. [src/main/java/com/apptasticsoftware/rssreader/AbstractRssReader.java [585-594]](https://github.com/w3stling/rssreader/pull/174/files#diff-5a097d88f39fdbd552c3310d7b5e1c547981bb185595f89a39dfa2d43982502cR585-R594) ```diff try { reader = xmlInputFactory.createXMLStreamReader(is); if (!readTimeout.isZero()) { parseWatchdog = EXECUTOR.schedule(this::close, readTimeout.toMillis(), TimeUnit.MILLISECONDS); } } catch (XMLStreamException e) { if (LOGGER.isLoggable(Level.WARNING)) { LOGGER.log(Level.WARNING, "Failed to process XML. ", e); } } +finally { + close(); +} ``` Suggestion importance[1-10]: 9 Why: Adding a finally block to ensure resources are closed is a best practice that prevents resource leaks, especially in the context of XML stream processing where exceptions might occur.	9
Possible issue	Improve the handling of potential null values in content encoding comparison ___ Replace the use of `Optional.of("gzip").equals(...)` with `Optional.equals(Optional.ofNullable(...))` to handle potential null values more gracefully. [src/main/java/com/apptasticsoftware/rssreader/AbstractRssReader.java [529-530]](https://github.com/w3stling/rssreader/pull/174/files#diff-5a097d88f39fdbd552c3310d7b5e1c547981bb185595f89a39dfa2d43982502cR529-R530) ```diff -if (Optional.of("gzip").equals(response.headers().firstValue("Content-Encoding"))) { +if (Optional.of("gzip").equals(Optional.ofNullable(response.headers().firstValue("Content-Encoding").orElse(null)))) { inputStream = new GZIPInputStream(inputStream); } ``` Suggestion importance[1-10]: 8 Why: The suggestion correctly addresses the potential issue of null values by using `Optional.ofNullable`, which is a more robust and safer approach for handling optional values.	8
Enhancement	Include exception stack trace in logging for better error diagnostics ___ Enhance the logging detail by including the exception stack trace in the log message. [src/main/java/com/apptasticsoftware/rssreader/util/Mapper.java [56-57]](https://github.com/w3stling/rssreader/pull/174/files#diff-715f5166b601a0e79c2bc86485bebf714fd7191397bd059631a20e24f4b0c46eR56-R57) ```diff if (LOGGER.isLoggable(Level.WARNING)) { - LOGGER.log(Level.WARNING, () -> String.format("Failed to convert %s. Message: %s", text, e.getMessage())); + LOGGER.log(Level.WARNING, "Failed to convert " + text, e); } ``` Suggestion importance[1-10]: 8 Why: Including the exception stack trace in the log message provides better error diagnostics, which is valuable for debugging and understanding the context of errors.	8
Enhancement	Improve the readability and consistency of exception messages ___ Use `String.format` for constructing the exception message to ensure consistent formatting and readability. [src/main/java/com/apptasticsoftware/rssreader/AbstractRssReader.java [525]](https://github.com/w3stling/rssreader/pull/174/files#diff-5a097d88f39fdbd552c3310d7b5e1c547981bb185595f89a39dfa2d43982502cR525-R525) ```diff -throw new IOException("Response http status code: " + response.statusCode()); +throw new IOException(String.format("Response HTTP status code: %d", response.statusCode())); ``` Suggestion importance[1-10]: 7 Why: The suggestion improves the readability and consistency of exception messages, which is beneficial for maintaining code quality and clarity.	7
