Description

org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer
is delegating the property parsing for camelContext to DefaultPropertiesParser.
DefaultPropertiesParse does not have support for System Properties Mode such as OVERRIDE, FALLBACK.

It's always taking System properties over provided properties. (OVERRIDE Mode)

DefaultPropertiesParser Line 299

private String doGetPropertyValue(String key) {
            String value = System.getProperty(key);
            if (value != null) {
                log.debug("Found a JVM system property: {} with value: {} to be used.", key, value);
            } else if (properties != null) {
                value = properties.getProperty(key);
            }
            return parseProperty(key, value, properties);
        }
