Six weeks ago [1] we began an effort to improve the quality of the Java codebase via ErrorProne static analysis, and promoting compiler warnings to errors. As of today, all of our Java projects have been migrated and this is now the default setting for Beam [2].
This was a community effort. The cleanup spanned 48 JIRA issues [3] and 46 pull requests [4]. I want to give a big thanks to everyone who helped out: Ismaël Mejía, Tim Robertson, Cade Markegard, and Teng Peng. Thanks!
