> The documentation at:
> http://karaf.apache.org/manual/latest/developers-guide/security-framework.html
> contains an example of using blueprint to configure a JAAS realm and uses the $[karaf.base]
property to specify the path to the properties file defining users and roles.  To ensure consistent
paths across platforms a PropertiesConverter is used however the example itself is broken
because it violates the XML XSD for http://www.osgi.org/xmlns/blueprint/v1.0.0.
> The example XML will not deploy complaining of an XML schema violation because of the
order of elements.
> The XML contains:
>     <ext:property-placeholder placeholder-prefix="$[" placeholder-suffix="]"/>
>     <type-converters>
>         <bean class="org.apache.karaf.jaas.modules.properties.PropertiesConverter"/>
>     </type-converters> 
> But the type-converters element (per the XSD) must follow the optional description element
and precede any others within the root blueprint element.  Re-ordering the XML like:
>     <type-converters>
>         <bean class="org.apache.karaf.jaas.modules.properties.PropertiesConverter"/>
>     </type-converters> 
>     <ext:property-placeholder placeholder-prefix="$[" placeholder-suffix="]"/>
> to properly place the ext:property-placeholder element AFTER the type-converters element
resolves the problem and allows it to deploy properly.
