Example 17 with SimpleModule

use of com.fasterxml.jackson.databind.module.SimpleModule in project jackson-databind by FasterXML.

the class TestSubtypes method testDefaultImplViaModule.

// [JACKSON-505]: ok to also default to mapping there might be for base type

        fail("Expected an exception");
    } catch (InvalidTypeIdException e) {
