It is cased by activemq's dependency of camel. Since activemq-core.jar is in
the $SMX_HOME/lib but the camel-core.jar is in the service-camel service engine
lib. They are loaded by different class loaders, so we get the
NoClassDefFoundError (not the ClassNotFoundException).
I think we can resolve this issue by moving the camel-core into $SMX_HOME/lib
or take camel out of activemq-core to break the cycle dependency.
Because camel-core have some jaxb dependency, I think the last option is the
best solution.
