[jira] [Created] (LUCENE-8165) ban Arrays.copyOfRange with forbidden APIs

Robert Muir created LUCENE-8165:
-----------------------------------

             Summary: ban Arrays.copyOfRange with forbidden APIs
                 Key: LUCENE-8165
                 URL: https://issues.apache.org/jira/browse/LUCENE-8165
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Robert Muir


This method is no good, because instead of throwing AIOOBE for bad bounds, it will silently fill with zeros (essentially silent corruption). Unfortunately it is used in quite a few places so replacing it with e.g. arrayCopy may uncover some interesting surprises.

See LUCENE-8164 for motivation.
