ISIS-1171: if missing, default datanucleus.schema.autoCreateAll to false, not
true (to avoid accidental modification of a target database).
> If DN autoCreate is missing, don't default to "true", instead default to
> "false".

> Key: ISIS-1171
> URL: https://issues.apache.org/jira/browse/ISIS-1171
> Project: Isis
> Issue Type: Improvement
> Components: Core
> Affects Versions: core-1.8.0
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Priority: Minor
> Fix For: 1.9.0
>
>
> With the current 1.8.0 behaviour, if an application did not specify the
> "datanucleus.autoCreateSchema" property (eg due to a typo), then the
> framework would default this property to "true". This could result in the
> target database being modified.
> So, instead, we should default this to "false", to avoid such accidents. Note
> that in 1.9.0 the name of this property changes to
> "datanucleus.schema.autoCreateAll", but the intent is the same.
> ~~~
> Also, note that there is similar functionality for validation;
> "datanucleus.autoValidateAll" is defaulted to true if missing. This
> behaviour does _not_ need to change as their are no ill side-effects. NB: in
> 1.9.0 note that the name of this property changes to
> "datanucleus.schema.autoValidateAll".
