When change log level debug, I see the following log.

"Detect Jakarta Commons Collections OrderedMap implementations"
If the injected type is not OrderedMap, can see that trying to create a new Map.
When using the existing Spring DM property, it is expected to create the same new map and try it, but there was no failure.
Why? Do I fail when I use Blueprint Property?
What am I missing? Is there a better alternative?
When I came back from solving other problems for a few days, I looked at the guide document of OSGI 7 standard and it was a very simple problem.
<bean id="filter" class="java.util.LinkedHashMap">
<argument>
<map>
<entry key="codecFilter" value-ref="dfCodec"/>
</map>
</argument>
</bean>
<bean id="filters"
class="org.apache.mina.core.filterchain.DefaultIoFilterChainBuilder">
<property name="filters" ref="filter"/>
</bean>
it works well
