/**
 * @deprecated Use version in maven artifact camel-ug-test-tools instead.
 * 
 * A DataSet that reads JSON encoded UG payloads from a file.
 * 
 * The file is assumed to contain a stream of objects used as part of one UG sync
 * event. UgMessage start and done messages with empty bodies will be inserted
 * before and after this stream.
 * 
 * Relevant UgMessage headers will be added to messages produced by this
 * dataset.
 * 
 * Example of use:
 *  * <bean id="ugDataSet" class="se.kth.infosys.camel.UgJsonDataSet">
 *   <property name="sourceFile" value="classpath:ug-data.json"/>
 *   <property name="size" value="32"/>
 * </bean>
 * ...
 * <from uri="dataset:ugDataSet" />
