Accessing (Jasypt) encrypted properties inside Camel Namspace'd elements

Issue

I have a blueprint camel route and I am trying to access encrypted password from a properties file inside their Camel components:

<cm:property-placeholder id="props" persistent-id="bluetest" update-strategy="reload" />

       <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="passwordEnvName" value="FUSE_ENCRYPTION_PASSWORD" />
                               </bean>
                       </property>
               </enc:encryptor>
       </enc:property-placeholder>

        <camel:sslContextParameters id="mySslContext">
            <camel:keyManagers keyPassword="{{keypass}\}">
                <camel:keyStore resource="serviceKeystore.jks" password="{{storepass}\}"/>
            </camel:keyManagers>
        </camel:sslContextParameters>

        <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="jetty:https://localhost:9000?sslContextParametersRef=#mySslContext"/>
            <log message="test"/>
        </route>
    </camelContext>

The value of “ keypass” and "storepass" were encrypted and with ENC(…) in the configuration file:

keypass=ENC(MKkuJDh3hwcSCd18jerTGg==)
storepass=ENC(k2oDCuqOZcDo+YDgUFtmUA==)

However, the property placeholder inside the element always returns encrypted value of "ENC(MKkuJDh3hwcSCd18jerTGg==)” rather than decrypted value. As a result, my camel-jetty consumer endpoint was always failed with error like:

19:05:42,352 | ERROR | l Console Thread | BlueprintCamelContext | 204 - org.apache.camel.camel-blueprint - 2.15.1.redhat-621084 | Error occurred during starting Camel: CamelContext(camel-1) due java.io.IOException: Keystore was tampered with, or password was incorrect
