[jira] [Created] (CASSANDRA-12381) Verify use of ByteBuffer.hasArray() in whole code base

Robert Stupp created CASSANDRA-12381:
----------------------------------------

             Summary: Verify use of ByteBuffer.hasArray() in whole code base
                 Key: CASSANDRA-12381
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12381
             Project: Cassandra
          Issue Type: Bug
            Reporter: Robert Stupp
            Priority: Minor
             Fix For: 2.1.x


As [noted here|https://docs.oracle.com/javase/8/docs/api/java/nio/ByteBuffer.html#allocateDirect-int-], a direct {{ByteBuffer}} can have a backing array.

If a direct {{ByteBuffer}} has a backing array, we should not make any assumption on how it is actually used.

This ticket is about to check whether uses of {{ByteBuffer.hasArray()}} need to be replaced with {{ByteBuffer.isDirect()}}.

(With CASSANDRA-11870 however, there is no way that such a direct {{ByteBuffer}} has a backing array.)
