> FindBugs is an open source program created by Bill Pugh and David Hovemeyer 
> which looks for bugs in Java code. It uses static analysis to identify 
> hundreds of different potential types of errors in Java programs.
> Although Spark is a Scala project, FindBugs is still helpful. For example, I 
> used it to find SPARK-1583 and SPARK-1589. However, the disadvantage is that 
> the report generated by FindBugs usually contains many false alarms for a 
> Scala project.
