    } catch (Throwable e) {
        namingStrategy = NameGeneratorPreferences.defaultNameGenerator();
    }
    // TODO: Modeler-controlled defaults for all the hardcoded boolean flags here.
    EntityMergeSupport merger = new EntityMergeSupport(namingStrategy, NamePatternMatcher.EXCLUDE_ALL, true, true, false);
    // see if we need to remove meaningful attributes...
