[jira] [Created] (LUCENE-6621) Unused variables

["Rishabh Patel (JIRA)" <ji...@apache.org>]

Rishabh Patel created LUCENE-6621:
-------------------------------------

             Summary: Unused variables
                 Key: LUCENE-6621
                 URL: https://issues.apache.org/jira/browse/LUCENE-6621
             Project: Lucene - Core
          Issue Type: Bug
          Components: modules/analysis
    Affects Versions: Trunk
            Reporter: Rishabh Patel
            Priority: Trivial


{code:title=Compile.java|borderStyle=solid}
public static void main(java.lang.String[] args) throws Exception {
...
  for (int i = 1; i < args.length; i++) {
      // System.out.println("[" + args[i] + "]");
      Diff diff = new Diff();
      int stems = 0;
      int words = 0;
...
{code}

In the file {{Compile.java}}, the variables {{stems}} and {{words}} are unused.
Although {{words}} gets incremented further in the file, it does not get referenced or used elsewhere.

{{stems}} is neither incremented nor used elsewhere in the project.

Are these variables redundant?
