Description

Using the following IDL:

@namespace("us.codemug")
protocol BooleanTestProtocol {
  void booleanInUnion(union{boolean, int, string} myunion);
}

and the following Java implementation:

package us.codemug;

import java.util.Map;
import org.apache.avro.AvroRemoteException;

public class BooleanTestResponder implements BooleanTestProtocol {

  public Void booleanInUnion(Object myunion) throws AvroRemoteException {
    print(myunion);
    return null;
  }

  private void print(Object value) {
    System.out.println("Type: " + value.getClass().getName());
    System.out.println("Value: " + value);
  }
}

When performing the IPC from python with the input:

args = dict()
args['myunion'] = True
requestor.request('booleanInUnion', args)

Produces this output at the server side:

Type: java.lang.Integer
Value: 1

The booleans are being converted to integers
