/**
 * This portlet implements several test cases for the JSR 362 TCK. The test case names
 * are defined in the /src/main/resources/xml-resources/additionalTCs.xml
 * file. The build process will integrate the test case names defined in the 
 * additionalTCs.xml file into the complete list of test case names for execution by the driver.
 *
 * This is the main portlet for the test cases. If the test cases call for events, this portlet
 * will initiate the events, but not process them. The processing is done in the companion 
 * portlet DispatcherReqRespTests2_SPEC2_19_ForwardServletResourceRequest_event
