             Summary: SynonymMap.Builder.join(String[], CharsRef) is untested and broken
                 Key: LUCENE-4842
                 URL: https://issues.apache.org/jira/browse/LUCENE-4842
             Project: Lucene - Core
          Issue Type: Bug
          Components: modules/analysis
            Reporter: Steve Rowe
            Assignee: Steve Rowe
            Priority: Minor


{{SynonymMap.Builder.join()}} throws {{ArrayIndexOutOfBounds}} when you give it more than one {{String}}: the amount it grows to add the word separator is off by one; it fails to set the length of the {{CharsRef}} it populates; and it needlessly calls {{CharsRef.grow()}} twice per word, first for the word separator and again for the word to be appended.
