[jira] [Created] (CASSANDRA-14906) FastByteOperations.UnsafeOperations fails to handle read only byte buffers correctly

Aleksandr Sorokoumov created CASSANDRA-14906:
------------------------------------------------

             Summary: FastByteOperations.UnsafeOperations fails to handle read only byte buffers correctly
                 Key: CASSANDRA-14906
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14906
             Project: Cassandra
          Issue Type: Bug
            Reporter: Aleksandr Sorokoumov
            Assignee: Aleksandr Sorokoumov
             Fix For: 4.x


If a buffer is read only it reports having no array, though it may well be backed by an array. Code in UnsafeOperation works under the impression that a buffer for which hasArray() == false is necessarily a direct buffer. Which is not the case.
