             Summary: Placeholders in XML - issue with enc: , cm: and 
ConfigAdmin updates
                 Key: ARIES-1655
                 URL: https://issues.apache.org/jira/browse/ARIES-1655
             Project: Aries
          Issue Type: Bug
          Components: Blueprint
            Reporter: Paolo Antinori


It seems there is an issue with token replacement when both {{cm:}} and 
{{enc:}} namespaces are involved:

Full reproducer inline since is short enough:

{code:xml}
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
           
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0";
           xmlns:enc="http://karaf.apache.org/xmlns/jasypt/v1.0.0";>
 
   <enc:property-placeholder>
    <enc:encryptor class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
      <property name="config">
        <bean 
class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
          <property name="algorithm" value="PBEWithMD5AndDES"/>
          <property name="password" value="ENCRYPTION_PASSWORD"/>
        </bean>
      </property>
    </enc:encryptor>
  </enc:property-placeholder>

    <cm:property-placeholder persistent-id="mytest"  update-strategy="reload">
      <cm:default-properties>
          <!-- <cm:property name="mykey" value="5f85Rg1mhRZkAwPiRK3H+w=="/> -->
          <!-- <cm:property name="token" value="ENC(${mykey})"/> -->
          <cm:property name="token" value="ENC(5f85Rg1mhRZkAwPiRK3H+w==)"/>
      </cm:default-properties>
  </cm:property-placeholder> 

  <camelContext id="blueprintContext" trace="false"
    xmlns="http://camel.apache.org/schema/blueprint";>

    <route>
      <from uri="timer:foo?fixedRate=true&amp;period=1000" />
      <setBody><simple>{{token}}</simple>
      </setBody>
      <log message="Outside of Camel Context ${body}" />
    </route>
  </camelContext>
 
</blueprint>
{code}

If the above blueprint file is deployed, it works as expected: camel is able to 
log lines containing the decrypted value of the encoded token.

But

if the value is changed at {{ConfigAdmin}} level, in Karaf with this command:

{code}
config:propset --pid mytest token 'ENC(5f85Rg1mhRZkAwPiRK3H+w==)'
{code}

The token is no longer unencrypted:

{code}
2017-01-09 15:07:24,666 | INFO  | #2 - timer://foo | route2                     
      | 232 - org.apache.camel.camel-core - 2.17.0.redhat-630187 | Outside of 
Camel Context ENC(5f85Rg1mhRZkAwPiRK3H+w==)
{code}

I have tried adding indirection, with the lines you can see commented out but I 
have not been able to make it work.

I have worked around the issue writing an implementation of 
{{org.osgi.service.cm.ConfigurationPlugin}} that gave me the functionality I 
needed but I wonder if this should just work out of the box:
