The schema suggest

<container qualifier="osgi" default="true">
<protocol type="jmx-osgi">
<property name="host">localhost</property>
<property name="port">1090</property>
<property name="urlPath">jmxrmi</property>
</protocol>
</container>

the parser however wants

<container qualifier="osgi" default="true">
<protocol type="jmx-osgi">
<configuration>
<property name="host">localhost</property>
<property name="port">1090</property>
<property name="urlPath">jmxrmi</property>
</configuration>
</protocol>
</container>

Note, the extra configuration element. Please add a test that validates various config files against the schema and parsed values
