Thanks for the work, I tried but unfortunately did not manage to reproduce the error outside of the Android Emulator, different combinations of both features either work or result in different exceptions.
Also trying with the latest version of Locale.java inside the Android Emulator also did not work. I still get the same error message. It seems there is some other difference in XMLBeans here which introduced this issue. Please note that the current version of the poi-on-android project is based on 4.1.2 and there removing the "namespace-prefixes" feature did make it work. I only get this when upgrading to newer versions of Apache POI. So something between Apache POI 4.12 and 5.2.0 (and the corresponding XMLBeans version) changed and introduced this error. Regards...
