Error record classes do not allow you to set the exception message or cause on
construction
-------------------------------------------------------------------------------------------
Key: AVRO-846
URL: https://issues.apache.org/jira/browse/AVRO-846
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.5.1
Reporter: Alex Miller
Generated error record classes create only a no-arg constructor, thus there is
no way to construct one that has a message. You can set the cause via the
initCause() method but it would be nice to also allow for that. It would be
nice to replicate all of the Throwable constructors instead of just the no arg
one.
The use case that prompted this question was one where the error record carried
a meaningful message from the server side. When you print stack traces or look
at them you most naturally look at the message in the exception rather than the
error record value within the AvroRemoteException.
We would like to be able to create a new copy of the exception that sets the
message from within the record's fields so that the error is more visible in
standard Java infrastructure. Alternately, error records could have a
well-known field or way to designate a message that could make their way into
the message of the client-side exception. I don't know how this problem
translates into other language bindings.
