GregWhitsitt updated AVRO-1457:
-------------------------------
Attachment: test.avdl
ByteBufferTest.java
> ReadOnly ByteBuffer serialization mutates original state 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
> Attachments: 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.
> I'll attach a simple test which shows the issue
