Robert Stupp reassigned CASSANDRA-12381:
----------------------------------------
Assignee: Robert Stupp
> 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
> Assignee: 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.)
