> ------------------------------------------------------------------
>
> Key: AVRO-2114
> URL: https://issues.apache.org/jira/browse/AVRO-2114
> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Niels Basjes
> Assignee: Niels Basjes
> Priority: Minor
> Fix For: 1.9.0
>
>
> If you have in Java the generated SpecificRecord structure and it has nested
> fields then finding the cause of the problem takes a while. The cause is that
> the system wraps the deeper runtime exception in another runtime exception
> and in the end it can become too much to dig through.
> Goal: make the exception in this kind of scenario easier to read.
> If you let this test fail
> https://github.com/apache/avro/blob/master/lang/java/ipc/src/test/java/org/apache/avro/specific/TestSpecificBuilderTree.java#L75
> the stacktrace you get looks like this:
> {code}
> org.apache.avro.AvroRuntimeException: org.apache.avro.AvroRuntimeException:
> org.apache.avro.AvroRuntimeException: Field networkAddress type:STRING pos:1
> not set and has no default value
