             Summary: Fix bug when using custom classloader
                 Key: AVRO-1247
                 URL: https://issues.apache.org/jira/browse/AVRO-1247
             Project: Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.7.3
            Reporter: Ben McCann


I created a SpecificResponder with a SpecificData which contains my custom classloader (Play Framework's custom classloader actually). However, it's a real pain to do because SpecificResponder.getDatumReader and SpecificResponder.getDatumWriter don't use the SpecificData that I passed in. When creating a new object those two methods should use the SpecificData object that was passed in the constructor.

  @Override
  protected DatumWriter<Object> getDatumWriter(Schema schema) {
// It currently uses SpecificData.INSTANCE which makes using a different ClassLoader very difficult
//    return new SpecificDatumWriter<Object>(schema);
    return new SpecificDatumWriter<Object>(schema, data);
  }

  @Override
  protected DatumReader<Object> getDatumReader(Schema actual, Schema expected) {
// It currently uses SpecificData.INSTANCE which makes using a different ClassLoader very difficult
//    return new SpecificDatumReader<Object>(actual, expected, data);
    return new SpecificDatumReader<Object>(actual, expected, data);
  }
