> Improve protocol type errors when invalid sizes are received
> ------------------------------------------------------------
>
> Key: KAFKA-3426
> URL: https://issues.apache.org/jira/browse/KAFKA-3426
> Project: Kafka
> Issue Type: Improvement
> Affects Versions: 0.9.0.0
> Reporter: Ismael Juma
> Assignee: Ismael Juma
> Fix For: 0.10.1.0, 0.10.0.0
>
>
> We currently don't perform much validation on the size value read by the
> protocol types. This means that we end up throwing exceptions like
> `BufferUnderflowException`, `NegativeArraySizeException`, etc. `Schema.read`
> catches these exceptions and adds some useful information like:
> {code}
> throw new SchemaException("Error reading field '" + fields[i].name +
> "': " +
> (e.getMessage() == null ?
> e.getClass().getName() : e.getMessage()));
> {code}
> We could do even better by throwing a `SchemaException` with a more user
> friendly message.
