    Description

      The project https://github.com/centic9/poi-on-android allows to run Apache POI as part of Android Apps and thus also uses XMLBeans.

      When trying to update to Apache POI 5.2.0, I saw that there is a problem with the SAX parser on Android as it fails when both features "namespaces" and "namespace-prefix" are set to true.

      XMLBeans currently does this in the class Locale.SaxLoader and thus an Android Application crashes with an error "The 'namespace-prefix' feature is not supported while the 'namespaces' feature is enabled."

       

      Therefore I  will introduce a system property which can be used to control the SAX feature "namespace-prefixes" to be able to set it to "false" if required.

       

      The full stacktrace is:
