Bug#902404: maven-ant-helper: Provider com.bea.xml.stream.MXParserFactory not found

[Emmanuel Bourg]

Thank you for the report Andrius. The missing class comes from
libstax-java. I guess this was a transitive dependency that got dropped
at some point, I'll get a look.

To work around this issue I recommend using maven-debian-helper instead
of maven-ant-helper. maven-ant-helper was used to bootstrap Maven
components, it shouldn't be used for new packages nowadays.
