-----------------------------------
While I think it is the same issue, I am not sure that the solution offered in
the other jira is correct. Is it possible to confirm?
> ResolveUnion in 1.6.3 thinks a HashMap is a Record.

> Key: AVRO-1100
> URL: https://issues.apache.org/jira/browse/AVRO-1100
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.6.3
> Environment: Windows, eclipse
> Reporter: Joe Gamache
> Attachments: IntegerMap.java, ReflectDataTest.java
>
>
> Getting an exception thrown on line 542 of ReflectData.java. Put a
> breakpoint there and found the following:
> 1. Datum is a HashMap with 119 entries.
> 2. If I select "getSchemaName(datum)" (line 539) and say inspect, it returns
> "java.util.HashMap"
> 3. The "indexByName" also being accessed on line 539 = {map=1, null=0}
> 4. In "getSchemaName" if I select "isMap(datum)" and say inspect, it returns
> "true" (this would then return "map" which DOES exist in the indexByName
> structure
> 5. However, still in "getSchemaName" if I select "isRecord(datum)" and say
> inspect, I also get back "true". This then returns
> "getRecordSchema(datum).getFullName(), which is where the java.util.HashMap
> from item #2 comes from. Since this is not in the "indexByName" map, I get
> an UnresolvedUntionException.
> Either "isRecord" needs to be fixed to not return true for Maps, or the test
> for "isMap" at line 556 needs to moved up ahead of the test for "isRecord".
> This works fine under 1.5.4, but breaks under 1.6.3. I have a JUnit test
> that reproduces this, if I can figure out how to attach it :), I will.
