> It may occasionally be desirable to programmatically get rid of or override a property value, this is generally allowed for by the .setProperty method, however:
> Once hbm2ddl.auto is set to something, there is no way to unset it, or set it to a value which would be equivalent to its being unset (or its undocumented). There is no remove or unset, or deleteProperty, and also setting it to null does not work.
> Due to issues such as HHH-2018, it may be necessary to programmatically 'get rid of' hbm2ddl.auto even if the end user (or some other mechanism) has specified a value for it in an external hibernate.properties file (or other method of setting hibernate properties).
