Project: Avro
Issue Type: Bug
Components: java, javascript, js

protocol eg:
{
"protocol": "Test",
"namespace": "test.avro",
"types": [
{
"type": "record",
"name": "AAA",
"fields": [
{
"name": "a",
"type": "string"
}
]
},
{
"type": "record",
"name": "BBB",
"fields": [
{
"name": "b",
"type": "string"
},
{
"name": "a",
"type": "AAA"
}
]
},
{
"type": "record",
"name": "CCC",
"fields": [
{
"name": "c",
"type": "string"
},

in java use cmd:java -jar D:\workspace-mars2\Avro\lib\avro-tools-1.8.1.jar compile protocol D:\new\Test.avpr D:\new is ok.
but in node.js code:
var avro = require("D:\\Soft\\nodejs\\node_modules\\avsc");
var protocol = avro.parse("./Test.avpr");
Prompt error message as below:
D:\Soft\nodejs\node_modules\avsc\lib\types.js:918
throw new Error(f('ambiguous unwrapped union: %j', this));
Error: ambiguous unwrapped union:["null",{"name":"test.avro.BBB","type":"record","fields":[{"name":"b","type":"string","order":"ascending","aliases":[]},{"name":"a","type":{"name":"test.avro.AAA","type":"record","fields":[{"name":"a","type":"string","order":"ascending","aliases":[]}],"aliases":[]},"order":"ascending","aliases":[]}],"aliases":[]},{"name":"test.avro.CCC","type":"record","fields":[{"name":"c","type":"string","order":"ascending","aliases":[]},{"name":"t","type":"int","order":"ascending","aliases":[]}],"aliases":[]}]
