----------------------------------------
Summary: Adjust Class loading for using XMLBeans on Android
Key: XMLBEANS-612
URL: https://issues.apache.org/jira/browse/XMLBEANS-612
Project: XMLBeans
Issue Type: New Feature
Affects Versions: Version 5.0.3
Reporter: Dominik Stadler
Assignee: Dominik Stadler
Fix For: Version 5.1.0
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:
