>             Project: Jackrabbit FileVault
>          Issue Type: Improvement
>          Components: vlt
>    Affects Versions: 3.4.0
>            Reporter: Christian Schneider
>            Priority: Critical
>
> We had an issue where an asset could not be imported because of a not yet 
> registered namespace.
> The error looked like this:
> {code:java}
> Caused by: javax.jcr.NamespaceException: Unknown namespace URI: 
> http://ns.adobe.com/xap/1.0/sType/ManifestItem#
>       at

>       ... 38 common frames omitted{code}
> The problem with this error reporting is that it only says the namespace is 
> unknown while swallowing the real error.
> By patching the filevault core bundle I was able to get the real error:
> {code:java}
> 20.07.2022 08:44:11.876 *ERROR* [Queue Processor for Subscriber agent 
> publishSubscriber] 
> org.apache.jackrabbit.vault.fs.impl.io.GenericArtifactHandler Error while 
> parsing null: {}
> org.xml.sax.SAXException: javax.jcr.AccessDeniedException: Failed to register 
> namespace mapping stMfs -> http://ns.adobe.com/xap/1.0/sType/ManifestItem#
>       at 
> org.apache.jackrabbit.vault.fs.impl.io.DocViewSAXImporter.startPrefixMapping(DocViewSAXImporter.java:546)
>       at  {code}
> I will provide a PR to fix the exception handling.
