> When working on PR [https://github.com/apache/lucene/pull/25,] we noticed that some dead code is not being caught during static analysis in gradle build, such as the *start* variable in the following code: [https://github.com/apache/lucene/blob/a5996dbecd4a6b4147d961260711a2cb6aeab3d3/lucene/facet/src/java/org/apache/lucene/facet/FacetsConfig.java#L446-L456]
> We may need to look at if additional javac compiler flag, or configuration for *error prone,* should be added to catch such bug as well as other potential ones.
