While testing the quickstarts against the latest Mars-based Fuse Camel tooling, I discovered that the camel-log quickstart has a value of "timer:foo?period=5s" which is invalid according to the validation rules and the docs.
According to the Camel documentation it appears the value should be "timer:foo?period=5000" for a 5 second wait. http://camel.apache.org/timer.html
When it is "5s" you see a validation error in the tooling now that says "The parameter period requires a numeric value."
This is a minor issue, but may trip up new users.
