[ https://svn.apache.org/r1598146 ]
AVRO-1457. Java: Fix Encoder so that offset in non-array-backed ByteBuffers is
not altered when written. Contributed by Rob Turner.
> ReadOnly ByteBuffer serialization state changes after writing
> -------------------------------------------------------------
>
> Key: AVRO-1457
> URL: https://issues.apache.org/jira/browse/AVRO-1457
> Project: Avro
> Issue Type: Bug
> Affects Versions: 1.7.4
> Reporter: GregWhitsitt
> Assignee: Rob Turner
> Fix For: 1.7.7
>
> Attachments: AVRO-1457.patch, ByteBufferTest.java, test.avdl
>
>
> Using the GenericDatumWriter specifically, writing out an avro containing a
> read-only ByteBuffer changes state of the original object, making it unusable
> after the initial write. Potentially either the ByteBuffer needs to be
> copied prior to writing if read-only, or the offset needs to be reset after
> writing.
> I'll attach a simple test which shows the issue
