Bas de Bakker created ABDERA-314:
------------------------------------
Summary: In OSGi, parser bundle cannot use StAX
Key: ABDERA-314
URL: https://issues.apache.org/jira/browse/ABDERA-314
Project: Abdera
Issue Type: Bug
Affects Versions: 1.1.3
Reporter: Bas de Bakker
This issue refers to a version 1.1.3 dated December 21, 2012 on the Apache
mirrors. The mailing lists only mention an 1.1.3 RC2, so I'm not sure if this
version is meant to be the final release version of 1.1.3.
I'm trying to use Abdera in an OSGi based server. However, this fails with
stacktraces like:
javax.xml.stream.FactoryConfigurationError: Requested factory

As Java includes StAX since version 6, I don't need Woodstox. So what I did was:
1. Remove the geronimo-stax_api and wstx-asl jars from the abdera-parser bundle
2. Remove them from the Bundle-ClassPath manifest header
3. Add javax.xml.stream and javax.xml.stream.util to its Import-Package header
This fixed the issue for me.
I would suggest doing the above. Anyone still using an ancient Java version
without StAX can include it as an external dependency.
