Jason Rutherglen updated LUCENE-1473:
-------------------------------------
Attachment: LUCENE-1473.patch
LUCENE-1473.patch
serialVersionUID added to the relevant classes manually. Defaulted to 10
because it does not matter, as long it is different between versions. Thought
of writing some code to go through the Lucene JAR, do an instanceof on the
classes for Serializable and then verify that the serialVersionUID is 10.
Term implements Externalizable.
SerializationUtils was adapted from WriteableUtils of Hadoop for writing VLong.
TestSerialization use case does term serialization and serializes an arbitrary
query to a file and compares them.
TODO:
- Implement Externalizable
- More unit tests? How to write a unit test for multiple versions?

> To maintain serialization compatibility between Lucene versions,
> serialVersionUID needs to be added to classes that implement
> java.io.Serializable. java.io.Externalizable may be implemented in classes
> for faster performance.
