-------------------------------------
Summary: Generated Java code still fails with union containing
logical type
Key: AVRO-3934
URL: https://issues.apache.org/jira/browse/AVRO-3934
Project: Apache Avro
Issue Type: Bug
Components: java, logical types
Affects Versions: 1.11.3, 1.9.2
Environment: apache maven, avro maven plugin, avro v1.11.3 or 1.9.2
(tried with both), code being generated in Java 8.
Faulty java generation happens in both maven running on intellij idea and on
jenkins pipelines.
Issue happens in both windows and linux.
Reporter: Joan Soto Targa
In our company we're using both 1.9.2 and 1.11.3 versions of avro compiling to
Java 8 and in both cases we have observed that bug AVRO-1981 is still active
and deserialization fails for nullable fields that have a logical type: happens
at least for both "uuid" (in version 1.11.3, previous one just ignores this
type) and "timestamp-millis" (in both versions).
The error we get for the uuid case when attempting to deserialize is:
{noformat}
java.lang.ClassCastException: class org.apache.avro.util.Utf8 cannot be cast to
class java.util.UUID
{noformat}
In the class code, we should be getting:
{code:java}
static {
MODEL$.addLogicalTypeConversion(new Conversions.UUIDConversion());
MODEL$.addLogicalTypeConversion(new
TimeConversions.TimestampMillisConversion());
ENCODER = new BinaryMessageEncoder(MODEL$, SCHEMA$);
DECODER = new BinaryMessageDecoder(MODEL$, SCHEMA$);
conversions = new org.apache.avro.Conversion<?>[] {
null,
null,
new org.apache.avro.Conversions.UUIDConversion(),
null,
new org.apache.avro.data.TimeConversions.TimestampMillisConversion(),
null
};
WRITER$ = MODEL$.createDatumWriter(SCHEMA$);
READER$ = MODEL$.createDatumReader(SCHEMA$);
}
{code}
but we get:
{code:java}
static {
MODEL$.addLogicalTypeConversion(new Conversions.UUIDConversion());
MODEL$.addLogicalTypeConversion(new
TimeConversions.TimestampMillisConversion());
ENCODER = new BinaryMessageEncoder(MODEL$, SCHEMA$);
DECODER = new BinaryMessageDecoder(MODEL$, SCHEMA$);
WRITER$ = MODEL$.createDatumWriter(SCHEMA$);
READER$ = MODEL$.createDatumReader(SCHEMA$);
}
{code}
