>                 URL: https://issues.apache.org/jira/browse/FELIX-1398
>             Project: Felix
>          Issue Type: Bug
>          Components: Framework
>    Affects Versions: felix-1.8.1

>         Attachments: apache-compendium-1.2.0-manifest.mf, osgi-compendium-4.1.0-manifest.mf
> An implementation of the XML parser service does not work with org.osgi.compendium-1.2.0
from Felix
> Caused by: javax.xml.parsers.FactoryConfigurationError: java.lang.ClassNotFoundException:
*** Class 'org.jboss.test.osgi.jbosgi92.bundleA.SAXParserFactoryImpl' was not found because
bundle 1 does not import 'org.jboss.test.osgi.jbosgi92.bundleA' even though bundle 5 does
export it. Additionally, the class is also available from the system class loader. There are
two fixes: 1) Add an import for 'org.jboss.test.osgi.jbosgi92.bundleA' to bundle 1; imports
are necessary for each class directly touched by bundle code or indirectly touched, such as
super classes if their methods are used. 2) Add package 'org.jboss.test.osgi.jbosgi92.bundleA'
to the 'org.osgi.framework.bootdelegation' property; a library or VM bug can cause classes
to be loaded by the wrong class loader. The first approach is preferable for preserving modularity.

> This however works fine with the original org.osg.compendium-4.1.0
