[jira] [Created] (RAT-139) FullTextMatchingLicense.prune uses inefficient deleteAtChar

Sebb created RAT-139:
------------------------

             Summary: FullTextMatchingLicense.prune uses inefficient deleteAtChar
                 Key: RAT-139
                 URL: https://issues.apache.org/jira/browse/RAT-139
             Project: Apache Rat
          Issue Type: Improvement
            Reporter: Sebb


FullTextMatchingLicense.prune is quite inefficient.

It first copies the entire string to a StringBuilder, then scans the buffer deleting characters that are not letters or digits.

It should be a lot quicker to just copy the letters and digits once, skipping the rest.
