Disabling type coercion

[Mantas Gridinas]

Consider the following snippet which passes json string with ascii value 5 (0x35), and expects deserialization result to be an integer.

        ObjectMapper o = new ObjectMapper();

        String json = "\"5\""; // notice json string rather than json number

        Integer result = o.readValue(json, Integer.class); // expect throws for wrong type

        System.out.println("Hello world!");

In default configuration this does not seem to throw mismatch exception. Which of the flags should be used to prevent type coercion? For enums I found FAIL_ON_NUMBERS_AS_ENUMS, but I couldn't seem to find an equivalent for general coercion.

Ah, the databind module contains allow scalar coercion feature which solves my problem
