PJ Fanning commented on XMLBEANS-597:
-------------------------------------
Another possibility is to change the SaxLoader code so that it sets the
namespace feature first and then sets the namespace-prefix feature but catches
any exceptions from the 2nd call and quietly ignores them (or just logs them).
> Improve support for using XMLBeans on Android

>
> Key: XMLBEANS-597
> URL: https://issues.apache.org/jira/browse/XMLBEANS-597
> Project: XMLBeans
> Issue Type: New Feature
> Affects Versions: Version 5.0.3
> Reporter: Dominik Stadler
> Assignee: Dominik Stadler
> Priority: Major
> Fix For: Version 5.1.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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:
