Kazuaki Ishizaki 5ad4735bda [SPARK-24529][BUILD][TEST-MAVEN] Add spotbugs into maven build process ... ## What changes were proposed in this pull request? This PR enables a Java bytecode check tool [spotbugs](https://spotbugs.github.io/) to avoid possible integer overflow at multiplication. When an violation is detected, the build process is stopped. Due to the tool limitation, some other checks will be enabled. In this PR, [these patterns](http://spotbugs-in-kengo-toda.readthedocs.io/en/lqc-list-detectors/detectors.html#findpuzzlers) in `FindPuzzlers` can be detected. This check is enabled at `compile` phase. Thus, `mvn compile` or `mvn package` launches this check. ## How was this patch tested?
