--------------------------------------------------------------

[~alex.parvulescu] and [~edivad], could you please review the above patch? It is really just to prevent OOME. First I thought we should also disable the built-in engine, but now I see it would require more changes. The above code should match the Oak 1.2 and newer behavior _if_ the built-in engine would be enabled there, _and_ no (Lucene or Solr) index is available. This is the case for some of the unit tests, and (for a very short time) just after creating a new Oak repository, at the very first startup.

> With Oak 1.0.x, the built-in full-text engine is used if no other full-text index is available. This is different than in newer versions of Oak, where the built-in engine is disabled in that case by default.
> I think it makes sense to backport this to Oak 1.0.x, so that all versions behave the same way. 
> This is to prevent out-of-memory problems if no full-text index is configured.
