Created attachment 38054 [details] example file causing forever rendering with XmlStreamReader My pptx corpus has some files which took forever to be rendered. The culprit was the double (or more) parsing of custom geometry parts via the XmlStreamReader interface. The XmlStreamReader is still used to parsed the preset shapes in the Common SL package (in the main module) which doesn't allow to use XmlBeans. But in XSLF, it's not necessary to parse the slides XmlBeans over and over again. Attached is a sample slide which causes that expensive execution flow.
