## Summary of Changes Hello, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request focuses on improving code quality and maintainability by re-enabling a specific Error Prone check and subsequently refactoring existing lambda expressions into more concise and idiomatic method references. This effort streamlines the codebase, making it easier to read and potentially more performant by leveraging Java's method reference capabilities. ### Highlights * **Error Prone Check Re-enabled**: The `UnnecessaryLambda` Error Prone check has been re-enabled by removing it from the `disabledChecks` list in `BeamModulePlugin.groovy`. This check flags lambdas that can be replaced by direct method implementations or method references. * **Lambda Refactoring**: Numerous lambda expressions across the codebase, particularly those assigned to `Function`, `BiFunction`, `Runnable`, `Supplier`, and `Predicate` interfaces, have been refactored into static or instance method references. This change improves code readability and adheres to the `UnnecessaryLambda` check's recommendations. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <details> <summary><b>Changelog</b></summary> * **buildSrc/src/main/groovy/org/apache/beam/gradle/BeamModulePlugin.groovy** * Removed 'UnnecessaryLambda' from the list of disabled Error Prone checks. * **runners/google-cloud-dataflow-java/worker/src/test/java/org/apache/beam/runners/dataflow/worker/StreamingDataflowWorkerTest.java** * Replaced a static `Function` lambda with a static helper method `emptyDataResponder`. * Updated all usages of the `EMPTY_DATA_RESPONDER` lambda to use the `emptyDataResponder` method reference. * **runners/google-cloud-dataflow-java/worker/src/test/java/org/apache/beam/runners/dataflow/worker/status/WorkerStatusPagesTest.java** * Removed unused `java.util.function.BooleanSupplier` import. * Replaced a `BooleanSupplier` lambda with a private method `mockHealthyIndicator` and updated its usage to a method reference. * **runners/google-cloud-dataflow-java/worker/src/test/java/org/apache/beam/runners/dataflow/worker/streaming/harness/SingleSourceWorkerHarnessTest.java** * Removed unused `java.util.function.Function` import. * Replaced `Runnable` and `Function` lambdas with private methods `waitForResources` and `computationStateFetcher`, and updated their usages to method references. * **runners/google-cloud-dataflow-java/worker/src/test/java/org/apache/beam/runners/dataflow/worker/windmill/work/refresh/ActiveWorkRefresherTest.java** * Replaced a static `Supplier<Instant>` lambda with a static helper method `aLongTimeAgo` and updated its usage to a method reference. * **runners/spark/3/src/main/java/org/apache/beam/runners/spark/structuredstreaming/translation/helpers/EncoderHelpers.java** * Removed unused `java.util.function.Function` import. * Replaced a static `Function` lambda with a static helper method `encoderFactory` and updated its usage to a method reference. * **sdks/java/core/src/main/java/org/apache/beam/sdk/fn/test/TestStreams.java** * Refactored `Consumer`, `Runnable`, and `Supplier` lambdas into static methods `throwingErrorHandler`, `noopRunnable`, and `alwaysTrueSupplier` respectively. * Updated calls to use the new static method references. * **sdks/java/core/src/main/java/org/apache/beam/sdk/util/construction/resources/PipelineResources.java** * Removed unused `java.util.function.Predicate` import. * Replaced a static `Predicate` lambda with a static helper method `isStageable` and updated its usage to a method reference. * **sdks/java/core/src/test/java/org/apache/beam/sdk/transforms/errorhandling/BadRecordRouterTest.java** * Removed unused `java.util.function.BiFunction` import. * Replaced a static `BiFunction` lambda with a static helper method `ignoreStacktraceMatcher` and updated its usage. * **sdks/java/core/src/test/java/org/apache/beam/sdk/util/UnboundedScheduledExecutorServiceTest.java** * Replaced static `Runnable` and `Callable` lambdas with static helper methods `runnable`, `callable`, and `failingCallable`. * Updated all usages of these lambdas to use the new static method references. * **sdks/java/io/amazon-web-services2/src/main/java/org/apache/beam/sdk/io/aws2/kinesis/EFOShardSubscribersPool.java** * Removed unused `java.util.function.BiConsumer` import. * Replaced a `BiConsumer` lambda with a private method `errorHandler` and updated its usage to a method reference. * **sdks/java/io/amazon-web-services2/src/main/java/org/apache/beam/sdk/io/aws2/kinesis/RateLimitPolicyFactory.java** * Replaced a static `Supplier<Duration>` lambda with a static helper method `defaultDelay` and updated its usage to a method reference. * **sdks/java/io/amazon-web-services2/src/main/java/org/apache/beam/sdk/io/aws2/sqs/SqsIO.java** * Replaced a `BiFunction` lambda with a private method `getLocked` within the `Dynamic` class and updated its usage to a method reference. * **sdks/java/io/kafka/src/test/java/org/apache/beam/sdk/io/kafka/KafkaIOReadImplementationCompatibilityTest.java** * Refactored `Function` lambdas `legacyDecoratorFunction` and `sdfDecoratorFunction` into private methods. * Updated their usages to use method references. </details> <details> <summary><b>Activity</b></summary> * The `UnnecessaryLambda` Error Prone check was re-enabled in the build configuration. * Multiple lambda expressions across various Java files were identified and refactored into method references or static helper methods to comply with the re-enabled check. </details> <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
