Is there any way to skip the check of the existing tables in SQLHelper class?

This is because for security reasons (lower-privileged database user). I need to use synonyms (oracle) in place of actual tables and it seems, looking at SQLHelper class, that nuxeo performs a preliminary check by table metadata that doesn't work when the synonyms are used.

Thank you in advance

More information:

I performed a test changed this row in org.nuxeo.ecm.directory.sql.SQLHelper in tableExists method:

ResultSet rs = metaData.getTables(null, schemaName, table.getPhysicalName(), new String[] { “TABLE” }); ResultSet rs = metaData.getTables(null, schemaName, table.getPhysicalName(), new String[] { “TABLE”, “VIEW”, “SYNONYM”});

and I haven't anymore errors
