The components registered in the config workspace under

javascript-models/config/engineConfiguration/exposedComponents

does not function on early versions of 1.8
The earliest version where it is known to work is 1.8.0_121-b13.

To reproduce,

• install java ... _66 or earlier.
• Install the javascript-model-samples module.
• Try to run the "browse contacts page"

Suggested fix:

• If possible, get it to work on earlier versions.
• Otherwise detect when someone tries to use it and display helpful message in the log about the problem and its resolution.
• Try to determine in which version it starts working.
• Document the issue in documentation.
