Anders Sundelin commented on AVRO-2072:
---------------------------------------
Please substitute [long] with [int] in my prior comment - long-to-double
conversion would always be lossy (both are 64-bit quantities). But my argument
about the method name still remains, it will pick the "first match", not
necessarily the "best match" (though its behaviour is according to the Avro
spec, afaik)
> ResolvingGrammarGenerator doesn't implement schema resolution correctly for
> unions

> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.7, 1.8.1
> Reporter: Nandor Kollar

> According to
> [specification|https://avro.apache.org/docs/current/spec.html#Schema+Resolution],
> int and long is promotable to float, but when using SchemaValidator, a union
> with a single int or long branch is not readable by an union with a float
> branch.
