Yes, I found the issue (I think ;) ).
I bet you are using Spring 5 by default.
Do you have spring-legacy repository added before adding activemq repo ?
The point is that: activemq-osgi "expects" spring schema from spring 4. As
spring changed the location in spring 5, activemq-osgi uses the "online"
version of the schema.
If you do:
{code:java}
karaf@root()> feature:repo-add spring-legacy
karaf@root()> feature:repo-add activemq 5.15.13
karaf@root()> feature:install activemq-broker
{code}
I guess it works.
The "offline" issue is related to Spring 5 used in the Karaf runtime.
I'm in the process of upgrading ActiveMQ to Spring 5 to avoid issue.

> {code:java}
> Temporary solution : Update the etc/activemq.xml root element which has been
> provided by the feature installation like this
> <beans xmlns="http://www.springframework.org/schema/beans";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:schemaLocation="http://www.springframework.org/schema/beans
> file:spring-beans-4.3.xsd
> http://activemq.apache.org/schema/core
> http://activemq.apache.org/schema/core/activemq-core.xsd";>
> and provided the spring-beans-4.3 at ${KARAF_HOME}. Than the instance was
> able to start again.
> {code}
> The error was gone in Karaf 4.2.8 but occured again in Karaf 4.2.9.
