--------------------------------------
Summary: Unable to use the copy builder with @java-class annotated
generated classes
Key: AVRO-2139
URL: https://issues.apache.org/jira/browse/AVRO-2139
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.8.2
Reporter: Auke van Leeuwen
Description:
When I'm using a schema with an {{@java-class}}, I can't seem to be using the
'copy' builder.
I think a piece of code says more than a thousands words:
{{.avdl}} snippet:
{noformat}
...
record Money {
Currency currency;
@java-class("java.math.BigDecimal")
string amount;
}
...
{noformat}
Test:
{noformat}
@Test
void test_copy_builder() {
Money original = Money.newBuilder()
.setAmount(BigDecimal.TEN)
.setCurrency(Currency.EUR)
.build();
Money duplicate = Money.newBuilder(original).build();
assertThat(duplicate, is(equalTo(original)));
}
{noformat}
Result:
{noformat}
java.lang.ClassCastException: org.apache.avro.util.Utf8 cannot be cast to
java.math.BigDecimal
