Hi Sven,
I managed to reproduce the issue and find out PropertyPlaceholderConfigurer
know nothing about the util:constant as a property.
You have to use it in [a different
way|http://stackoverflow.com/questions/7309956/how-to-reference-constant-in-attribute-in-spring].
I did some work to enable the configuration of "ignoreResourceNotFound", so you
don't need to addition camel:propertyPlaceholder to the camel context there,
the bridgePropertyPlaceHolder could be.
{code}
<bean id="bridgePropertyPlaceHolder"
class="org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true"/>
<property name="locations">
<list>
<value>classpath:test.properties</value>
</list>
</property>
</bean>
{code}
