Description

Camel-parent 17.0 uses logback-classic:1.1.5 and slf4j-api:1.7.13

These are not compatible and produce the following error:
java.lang.NoClassDefFoundError: org/slf4j/event/LoggingEvent

See the following page:
http://www.slf4j.org/codes.html

Logback-classic version 1.1.4 and later require slf4j-api version 1.7.15 or later.
With an earlier slf4j-api.jar in the classpath, attempting introspection of a Logger instance returned by logback version 1.1.4 or later will result in a NoClassDefFoundError similar to that shown below....
