问题 In many projects, I have came across this exception. What could be the reason for this exception ? According to my knowledge, it can be because of inconsistent version usage.

问题 I'm trying to externalize my Camel Spring (Camel 2.20.2; Spring 4.3.14) configuration into an application.properties property file. This property file has the following content: net.sender1.port = 47000 net.sender1.address = 127.255.255.255 The application.properties file resides within src/main/resources and is copied to the target jar by the maven-shade-plugin.
