MarshallerWriteContext.objectMarshallingStrategyStore contains an unpredictable list of ObjectMarshallingStrategy objects which can break WorkItemInfo unmarshalling (wrt backwards compatibility)

public static void writeWorkItem(MarshallerWriteContext context,
                                 WorkItem workItem) throws IOException {
    // ... other code

    for ( String key : parameters.keySet() ) {
        Object object = parameters.get( key );
        if ( object != null ) {
            stream.writeUTF( key );
            // Next 2 lines: we store the _index_ of the ObjectMarshallingStrategy object in the stream
            int index = context.objectMarshallingStrategyStore.getStrategy( object );*
            stream.writeInt( index );*
            ObjectMarshallingStrategy strategy = context.objectMarshallingStrategyStore.getStrategy( index );
            if ( strategy.accept( object ) ) {
                strategy.write( stream,
                                object );
            }
        }

    }
