not working with GWT 2.2.0

[GoogleCodeExporter]

What steps will reproduce the problem?
1. use syncproxy with GWT 2.2.0 project in server

What version of the product are you using? On what operating system?
MAC OS - GAE 1.4.2 & GWT 2.2.0 - eclipse

Error:
Caused by: com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: 
This application is out of date, please click the refresh button on your 
browser. ( Expecting version 6 from server, got 7. )

This was hap with old project with new GWT too..i changed lib jars n it worked. 
Might do the trick.

Please provide any additional information below.

I make it work by comment following line 359:

// serializationPolicy.validateDeserialize(instanceClass);

Hi
this is because of the inheritance of final members, when these are used on 
runtime the >compile time< inherited values are used, instead of the Runtime 
values!

the solution is to use reflection in the class loading to reflect the GWT 
engine avaliable at run time 

here is a piece of code to paste at head of the 
AbstractSerializationStreamReader class:
public class SyncClientSerializationStreamReader extends 
AbstractSerializationStreamReader {

    public static int SERIALIZATION_STREAM_VERSION;//used for cross gwt version compatibility as the compiled file imports the GWT version directly into the file
    public static int SERIALIZATION_STREAM_MIN_VERSION;
    //public static char RPC_SEPARATOR_CHAR;

    static {
        try {
            SERIALIZATION_STREAM_VERSION = AbstractSerializationStreamReader.class.getField("SERIALIZATION_STREAM_VERSION").getInt(null);
            SERIALIZATION_STREAM_MIN_VERSION = AbstractSerializationStreamReader.class.getField("SERIALIZATION_STREAM_MIN_VERSION").getInt(null);
            //RPC_SEPARATOR_CHAR=AbstractSerializationStreamReader.class.getField("RPC_SEPARATOR_CHAR").getChar(null);
        }
        catch (Exception e) {
        }
    }

==============================
another piece of code you might want to replace is at the prepareToRead method:
the updated method allow the use of versions between the 
MIN_SERIALIZATION_VERSION & SERIALIZATION_VERSION while the original only 
allowed SERIALIZATION_VERSION

   public void prepareToRead(String encoded) throws SerializationException {
        parse(encoded);
        index = results.size();
        super.prepareToRead(encoded);

        if (getVersion()<SERIALIZATION_STREAM_MIN_VERSION ||
                getVersion() >SERIALIZATION_STREAM_VERSION) {               
                    throw new IncompatibleRemoteServiceException("Expecting version between "
            + SERIALIZATION_STREAM_MIN_VERSION + " and "
            + SERIALIZATION_STREAM_VERSION + " from client, got " + getVersion()
            + ".");
        }

        buildStringTable();
    }
