             Summary: Specific record hashCode() with union including "java-class" throws exception
                 Key: AVRO-2462
                 URL: https://issues.apache.org/jira/browse/AVRO-2462
             Project: Apache Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.9.0, 1.7.7
            Reporter: Ryan Skraba


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
