             Summary: 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".
