Nandor Kollar commented on AVRO-2072:
-------------------------------------
[~zolyfarkas] I don't see any test failure, guess you executed tests on your
forked version instead of Apache master. Looks like
[intUnionIsNotConvertedToFloatUnion
|https://github.com/zolyfarkas/avro/blob/trunk/lang/java/avro/src/test/java/org/apache/avro/TestReadingWritingDataInEvolvedSchemas.java#L158]
and
[longUnionIsNotConvertedToFloatUnion|https://github.com/zolyfarkas/avro/blob/trunk/lang/java/avro/src/test/java/org/apache/avro/TestReadingWritingDataInEvolvedSchemas.java#L181]
are negative test: testing exactly what this Jira intends to fix right? Are
these tests your own test cases, or this was merged with a patch available
Jira, which is not yet merged to upstream trunk? As of the last test case, I'm
not sure what is the problem.

> 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.
