Hi, I found out package-info.java in the package org.apache.karaf.features.internal.model.processing contains
@XmlSchema(namespace = "http://karaf.apache.org/xmlns/features-processing/v1.0.0";, elementFormDefault = XmlNsForm.QUALIFIED, attributeFormDefault = XmlNsForm.UNQUALIFIED, xmlns = { @XmlNs(prefix = "", namespaceURI = FEATURES_PROCESSING_NS), @XmlNs(prefix = "f", namespaceURI = FeaturesNamespaces.URI_CURRENT) } ) These annotations are ignored when using Java 11, I have no idea why, but looks like a bug to me. Kind regards, Steven On Sun, Nov 28, 2021 at 12:05 PM Steven Huypens <[email protected]> wrote: > Hi Bernd, > > I must correct myself. Adding the 'ns3'-prefix to all of the children does > help.
