Camel 2.10 introduced the BridgePropertyPlaceholderConfigurer bean as a replacement of the Spring <context:property-placeholder>.
- may ignore missing property files (ignore-resource-not-found="true")
- falls back to system properties if a requested property could not be
found in the (potentially non-existent) properties file.
This functionality is not available in the BridgePropertyPlaceholderConfigurer. It would be great if it could be added.
