> Hi,
> I'm not sure where to send this so please let me know if I should send it
> somewhere else!
> Maybe this is just the case in 1.7.3, but it seems that ByteBufferTest is not
> actually run by Maven (because it's not named TestByteBuffer, so it doesn't
> match the test rules), and I am getting failures on its test() method if I
> force it to run. Specifically, this is happening:
> The test's X class has two fields, X.name (a String) and X.content (a
> ByteBuffer). It seems they are expected to maintain that order by the reader
> and writer.
> The writer first writes X.name as a String to its local buffer.
> The writer calls BufferedBinaryEncoder.writeFixed(ByteBuffer) to write
> X.content. If the size of the content exceeds 2048 bytes (bulkLimit),
> writeFixed() bypasses the local buffer and writes directly to the underlying
> sink (which was previously empty).
> The X.name String is then flushed to the sink after X.content, thus reversing
> the order of the fields.
> The reader fails because it is expecting the fields in the original order (as
> the schema and class both specify).
> Also, if the size of X.content is less than 2048 bytes, the contents are in
> expected order and the test passes.
> The actual reported error message is:
> Tests in error:
> test(org.apache.avro.reflect.TestByteBuffer): java.io.IOException: Block read
> partially, the data may be corrupt
> Anyway, I don't know how important this functionality is, but in any case, it
> doesn't appear to be tested in the current Maven setup. Just wanted to let
> you know!
> Regards,
> Judy Hay
