NotSerializableException when NumericField gets serialized in JMSBackendQueueProcessor
--------------------------------------------------------------------------------------

                 Key: HSEARCH-681
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-681
             Project: Hibernate Search
          Issue Type: Bug
    Affects Versions: 3.3.0.Final
         Environment: Master-Slave-Architecture
            Reporter: Katrin E.


We have a master-slave-architecture which delegates an index update to the master. We have NumericFields in the index to perform NumericRangeQueries. When the slave tries to inform the master via JMSBackendQueueProcessor the object including a NumericField gets serialized. A NotSerializableException occurs on a NumericTokenStream. The NumericField extends AbstractField, which implements Serializable, but it cannot be serialized because it stores the precisionStep in the underlying NumericTokenStream, which is not serializable.

This might be a lucene issue, but Hibernate Search gets affected for NumericRangeQueries. There is an issue on the lucene jira as well but isn't resolved yet:
https://issues.apache.org/jira/browse/LUCENE-2707

Here is a code snippet to test the serialization of a NumericField:

NumericField number = new NumericField("number", 4);
number.setFloatValue(42f);

try {
    FileOutputStream fout = new FileOutputStream("number.txt");
    ObjectOutputStream oos = new ObjectOutputStream(fout);
    oos.writeObject(number);
    oos.close();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
