--------------------------------

             Summary: PropertiesComponent gets initialized by util:constant
                 Key: CAMEL-7488
                 URL: https://issues.apache.org/jira/browse/CAMEL-7488
             Project: Camel
          Issue Type: Bug
          Components: camel-core, camel-spring
    Affects Versions: 2.13.1, 2.13.0
            Reporter: Sven Nold


Using BridgePropertyPlaceholderConfigurer & Spring util constant namespace  to 
reference a static field, the Properties Component gets initialized with this 
constant.

{code:xml|title=camelContext.xml }
<util:constant static-field="anypackage.CONSTANT_1"/>

<bean id="bridgePropertyPlaceHolder" 
class="org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer">
    <property name="locations">
      <list>
        <value>classpath:test.properties</value>
      </list>
    </property>
</bean>

<camel:camelContext xmlns="http://camel.apache.org/schema/spring";>
    <camel:route>
      <camel:from uri="direct://ignore" />
      <camel:setBody>
        <camel:simple>{{testProperty}}</camel:simple>
      </camel:setBody>
      <camel:to uri="mock://ignore" />
    </camel:route>
</camel:camelContext>   
{code}

Will produce following Stacktrace (constant contained '>>This will be loaded as 
location; but I am simply a constant<<'):

Caused by: java.io.FileNotFoundException: Properties file >>This will be loaded 
as location; but I am simply a constant<< not found in classpath

My current workaround was to specify propertyPlaceholder with empty location in 
 camelContext ...

{code:xml|title=camelContext.xml }
<!-- same as above -->
<camel:camelContext xmlns="http://camel.apache.org/schema/spring";>
    <!-- location and id are mandatory -->
    <camel:propertyPlaceholder id="stupidMandatoryId" location=""/>
    <camel:route>
      <camel:from uri="direct://ignore" />
      <camel:setBody>
        <camel:simple>{{testProperty}}</camel:simple>
      </camel:setBody>
      <camel:to uri="mock://ignore" />
    </camel:route>
</camel:camelContext>   
{code}
