> Key: AVRO-2471
> URL: https://issues.apache.org/jira/browse/AVRO-2471
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.9.0
> Reporter: Marek Tracz
> Assignee: Ryan Skraba
> Priority: Major
>
> Field in schema: (there is no single field with timestamp-millis logical type)
> {code:java}
> {
> "name": "RECORDING_TIME",
> "type": [
> "null",
> {
> "type": "long",
> "logicalType": "timestamp-micros"
> }
> ],
> "default": null
> }
> {code}
> Maven plugin configuration:
> {code:xml}
> <plugin>
> <groupId>org.apache.avro</groupId>
> <artifactId>avro-maven-plugin</artifactId>
> <version>1.9.0</version>
> <executions>
> <execution>
> <goals>

> <configuration>
> <stringType>String</stringType>
> <enableDecimalLogicalType>true</enableDecimalLogicalType>
> <sourceDirectory>${project.basedir}/src/main/resources/</sourceDirectory>
> </configuration>
> </execution>
> </executions>
> </plugin>
> {code}
> Part of the generated class:
> {code:java}
> private static SpecificData MODEL$ = new SpecificData();
> static {
> MODEL$.addLogicalTypeConversion(new org.apache.avro.data.TimeConversions.DateConversion());
> MODEL$.addLogicalTypeConversion(new org.apache.avro.data.TimeConversions.TimestampMillisConversion()); // <--- this should be TimestampMicrosConversion
> MODEL$.addLogicalTypeConversion(new org.apache.avro.Conversions.DecimalConversion());
> }
> {code}
> For example this code:
> {code:java}
> Data data = Data.newBuilder()
> .setRECORDINGTIME(Instant.now())
> .build();
> {code}
> Fails during comparison:
> {noformat}

> When manually changed to *org.apache.avro.data.TimeConversions.TimestampMicrosConversion* everything works properly.
