> Key: AVRO-2462
> URL: https://issues.apache.org/jira/browse/AVRO-2462
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.7, 1.9.0
> Reporter: Ryan Skraba
> Assignee: Ryan Skraba
> Priority: Major
> Fix For: 1.9.1
>
>
> Given a specific record generated from the following avsc:
> {code:java}
> {
> "type": "record",
> "name": "Lifetime",
> "fields": [
> {"name": "name", "type": "string"},
> {"name": "birth",
> "type": {"type": "string", "java-class": "java.util.Date"}},
> {"name": "death",
> "type": ["null",
> {"type": "string", "java-class": "java.util.Date"}],
> "default": null
> }
> ]
> }{code}
> birth is a required field and death is a nullable field.
> The following code works (death is null):
> {code:java}
> Lifetime ws = Lifetime.newBuilder().setName("William Shakespeare")
> .setBirth(new Date(-12801286800000L)).build();
> long x = ws.hashCode();{code}
> Setting the death field is broken:
> {code:java}
> ws.setDeath(new Date(-11161414800000L));
> long y = ws.hashCode();{code}
> The following exception is thrown:
> {code:java}
> org.apache.avro.AvroRuntimeException: Unknown datum type java.util.Date: Sat Apr 23 00:00:00 CET 1616
