> Java ErrorProne static analysis was [recently 
> enabled|https://github.com/apache/beam/pull/5161] in the Gradle build 
> process, but only as warnings. ErrorProne errors are generally useful and 
> easy to fix. Some work was done to [make sdks-java-core 
> ErrorProne-clean|https://github.com/apache/beam/pull/5319] and add 
> enforcement. This task is clean ErrorProne warnings and add enforcement in 
> {{beam-runners-reference-java}} and {{beam-runners-reference-job-server}}. 
> Additional context discussed on the [dev 
> list|https://lists.apache.org/thread.html/95aae2785c3cd728c2d3378cbdff2a7ba19caffcd4faa2049d2e2f46@%3Cdev.beam.apache.org%3E].
> Fixing this issue will involve:
> # Follow instructions in the [Contribution 
> Guide|https://beam.apache.org/contribute/] to set up a {{beam}} development 
> environment.
> # Run the following command to compile and run ErrorProne analysis on the 
> project: {{./gradlew :beam-runners-reference-java:assemble 
> :beam-runners-reference-job-server:assemble}}
> # Fix each ErrorProne warning from the {{runners/reference/}} directory.
> # In {{runners/reference/java/build.gradle}} and 
> {{runners/reference/job-server/build.gradle}}, add {{failOnWarning: true}} to 
> the call the {{applyJavaNature()}} 
> ([example|https://github.com/apache/beam/pull/5319/files#diff-9390c20635aed5f42f83b97506a87333R20]).
