> Key: AVRO-2836
> URL: https://issues.apache.org/jira/browse/AVRO-2836
> Project: Apache Avro
> Issue Type: Bug
> Components: java, logical types
> Affects Versions: 1.9.2
> Reporter: Matthew McMahon
> Assignee: Matthew McMahon
> Priority: Major
> Attachments: AVRO-2836.patch
>
>
> I have updated to Avro 1.9.2 using the avro-maven-plugin to generate the
> specific types.
> This is working nicely, except noticed the case of:
> {code:java}
> "fields": [
> {
> "name": "unionOfFixedDecimal",
> "type": ["null", {
> "namespace": "org.apache.avro.codegentest.testdata",
> "name": "FixedInUnion",
> "type": "fixed",
> "size": 12,
> "logicalType": "decimal",
> "precision": 28,
> "scale": 15
> }]
> }] {code}
> This is a fixed type that has a logical type of decimal.
> When the source is generated, the type is BigDecimal. However the
> DecimalConversion is missing and then it breaks when used.
> It seems easy to workaround by manually adding the logical conversion before
> using.
> However the fix seems to be in
> SpecificCompiler#getClassNamesOfPrimitiveFields which is used by
> #getUsedConversionClasses
