NoSuchComponentException when set update-strategy="reload" on cm:property-placeholder

Hi,

Given a blueprint xml likes this:

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
        xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0">

    <cm:property-placeholder persistent-id="abc" update-strategy="reload">
        <cm:default-properties>
            <cm:property name="key1" value="value1" />
            <cm:property name="key2" value="value2" />
        </cm:default-properties>
    </cm:property-placeholder>

    <bean id="myBean" class="org.abc.Abc">
        <property name="mykey1" value="key1"/>
        <property name="mykey1" value="key1"/>
    </bean>

    <service interface="org.abc.interface" ref="myBean"/>

</blueprint>

Which uses cm:property-placeholder to read properties from etc/abc.cfg and expose an osgi service.
The problem here is:  in case there is no abc.cfg existing in the etc/ folder, and set update-strategy="reload" , (be default, update-strategy="none" which works ok but can't auto reload the value of properties ) then, the NoSuchComponentException will be thrown.

Any suggestions? Thanks.
