------------------------------------
Summary: BigDecimal not supported in GenericData.getSchemaName()
method
Key: AVRO-3654
URL: https://issues.apache.org/jira/browse/AVRO-3654
Project: Apache Avro
Issue Type: Improvement
Components: java
Affects Versions: 1.11.1
Reporter: Emmanuel Brard
When trying to add a `GenericRecord` in a Java set, the hashcode computation
code is called.
If a Union contains a decimal logical type which is mapped with a `BigDecimal`
in Java, the call to `add` will fail with:
{code}

{code}
The method `getSchemaName` does not handle the BigDecimal Java type, which is
used by the `DecimalConversion`.
