MG>MultiPartRequestWrapper is set in these files: <BR>
MG>org.apache.struts2.dispatcher.Dispatcher.wrapRequest<BR>MG>org.apache.struts2.dispatcher.Dispatcher.cleanupRequest<BR>MG>org.apache.struts2.interceptor.FIleUploadInterceptor.intercept<BR>
If you think it is a bug you can create another jira.
MG>suggest testing getFileItems(String) with FileUploadInterceptorTest.java
