      In 9.1 and later, trying to get a property from a document fetched through unrestricted code (UnrestrictedSessionRunner or Framework#doPrivileged) outside the unrestricted context throws the following exception if the data model including the property hasn't been loaded before:

      "NuxeoException: The DocumentModel is not associated to an open CoreSession"

      Possible solutions are:

      • Fetch the property instead of the whole document inside the unrestricted code (queryAndFetch).
      • Call detach(true) on the document within the unrestricted code.
      • Prefetch the schema declaring the property.

      Description

      NXP-3529 introduced org.nuxeo.ecm.core.strictlazyloading to prevent from automatically re-attaching a detached document when using DocumentModel APIs that doing lazy loading (datamodel, system property, lock, acl, lifecycle).

      This means that we re-create temporary sessions at code locations not well determined, which prevents good analysis of session usage.

      —> prevent automatic reconnect of a DocumentModel. A DocumentModel should be either used in the context where its session is still open, or it should be explicitly detached.
