---------------------------------
Summary: Improve static analysis to catch dead code and other
potential bugs
Key: LUCENE-9856
URL: https://issues.apache.org/jira/browse/LUCENE-9856
Project: Lucene - Core
Issue Type: Improvement
Components: general/build
Reporter: Zach Chen
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.
