> With the update of Karaf from 4.2.1 to 4.2.2 I found the following error:
> Caused by: java.lang.LinkageError: loader constraint violation: when 
> resolving method 
> "javax.xml.soap.SOAPMessage.createAttachmentPart(Ljavax/activation/DataHandler;)Ljavax/xml/soap/AttachmentPart;"
>  the class loader "<unnamed>" (instance of 
> [org.apache.felix.framework.BundleWiringImpl$BundleClassLoader@2febf41d|mailto:org.apache.felix.framework.BundleWiringImpl$BundleClassLoader@2febf41d],
>  child of 
> [java.net.URLClassLoader@3fee9989|mailto:java.net.URLClassLoader@3fee9989]) 
> of the current class, com/sap/it/cxf/xi/XIUtils, and the class loader 
> <bootstrap> for the method's defining class, javax/xml/soap/SOAPMessage, have 
> different Class objects for the type javax/activation/DataHandler used in the 
> signature
>  
> I think this came in with this change: 
> https://issues.apache.org/jira/browse/KARAF-5989
>  
> Since the servicemix javax.activation bundle is not part of the framework 
> bundle anymore, it has to load it from the jdk and it will not import it from 
> the servicemix bundle (see change above).
> Other bundles correctly importing javax.activation will get it from the 
> servicemix bundle.
> This can lead to the linkage error outlined above.
