EnkiFindBugsPlugin

To aid in detecting uses of == on repository objects, Enki contains a FindBugs plugin that will detect use of the == and != operators on the javax.jmi.reflect.RefObject interface and its sub-interfaces and implementations.

Note that FindBugs is a static analysis tool and therefore cannot detect this error if the objects in question have been cast to java.lang.Object.

The Farrago build script contains a FindBugs target which can be adapted to use Enki's plugin:

• Copy eigenbase-enki-xxx-findbugs.jar into thirdparty/findbugs/plugin

At this point Farrago's findbugs target should automatically detect the RefObject equality error in addition to all the errors FindBugs normally detects. The findbugs target in Farrago can be adapted to use in other projects.

To focus on RefObject equality errors,

• Extract the file filter.xml from the Enki FindBugs plugin JAR.
• Set the FindBugs Ant task's includeFilter attribute to refer to the file's location.

Now FindBugs will detect only the RefObject equality error.
