Auto-mime not working for content > 32 KB but < 64 KB

[markleusink]

There seems to be an issue with the auto-mime setting and 'large summary' feature of a database. This commit (https://github.com/OpenNTF/org.openntf.domino/commit/321ffde49f56a03f21dfac5e27befd846530f4ff) increases the amount of data that is allowed in a single field from 32 KB to 64 KB, but those limits only apply when the 'large summary' feature has been enabled.

If you now try to store data that is > 32 KB but 64 KB, the data isn't automatically serialized and an error is thrown. If you try to store > 64 KB in a field, it is still properly serialized into a Mime object.

Tested this on Domino 12.0.1 with the ODA 12.0.1 release.

This is also related to https://github.com/OpenNTF/org.openntf.domino/issues/175.

Domino limits are described here: https://help.hcltechsw.com/dom_designer/11.0.1/basic/H_NOTES_AND_DOMINO_KNOWN_LIMITS.html https://help.hcltechsw.com/domino/12.0.0/admin/ods_55_introduced_in_domino_12.html
