> ---------------------------------------------------
> 
> 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.
