---------------------------------
Summary: 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.
