There should be a try/catch block for ClassCastException here.

> Key: AVRO-1847
> URL: https://issues.apache.org/jira/browse/AVRO-1847
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.0
> Reporter: Yibing Shi
> Attachments: AVRO-1847.1.patch, AVRO-1847.2.patch, AVRO-1847.3.patch,
> AVRO-1847.4.patch
>
>
> Version 1.8.0 has added the support of logical types. A conversion class
> (Conversions.DecimalConversion) has also been added for decimal type.
> However, the IDL compiler still uses ByteBuffer for decimal types, which is
> not the same behaviour as data, time or timestamp type (added in AVRO-1684).
