> portlet.xml parsing was previously very tolerant with respect to out-of-order elements (XSD kinda sucks for this), thus silently allowing portlet.xml that were not strictly valid according to portlet-app_2_0.xsd. The new staxnav parser, on the other hand, is a lot stricter (while still not validating) meaning that it will silently discard unexpected (in particular, out-of-order) elements, resulting in portlet metadata that previously was imported, now being silently discarded. While this is not strictly a bug (after all, the portlet.xml that result in errors are invalid), this is a rather big behavioral change compounded with the fact that the new parser silently discards information resulting in errors showing up much later than the parsing process and without any informational context that the user could use to fix the issue... :(
