Unable to start when there is no context service

[janb87]

The Content Delivery instance I'm using has no context service installed (there is no web service available).

DXA fails upon initialization when I run it. I tried enabling / disabling adf but this doesn't make any difference. I'm running this against the latest 1.7.0-SNAPSHOT.

Stack trace of the issue.

Relates to #70

Internal ID: TSI-2200. To reproduce the issue you have to remove the capability. Just disabling service is not enough.

Fixed in DXA 1.7

I've looked at the code changes and the issue is only partially solved.

In our scenario "public Map<String, Object> getContextClaims(String aspectName) throws DxaException {" would always throw an exception on every request.

@azarakovsky What are your suggestions on fixing this? Should we extend something to overwrite this behavior?

[azarakovskiy]

@janb87 I don't really understand. It seems you're trying to use ContextServiceClaimsProvider without Context Service. This will never work of course, you have to either switch to ADF or enable Context Service.
