#893 Disable Jackson ObjectMapper FAIL_ON_UNKNOWN_PROPERTIES Deserialization Feature by default

[amiriahmad72]

Edit JacksonDeserializer constructor with claimTypeMap argument:

public JacksonDeserializer(Map<String, Class<?>> claimTypeMap) {
    this(claimTypeMap, false);
}

public JacksonDeserializer(Map<String, Class<?>> claimTypeMap, boolean failOnUnknownProperties) {
    // DO NOT reuse JacksonSerializer.DEFAULT_OBJECT_MAPPER as this could result in sharing the custom deserializer
    // between instances
    this(new ObjectMapper());
    Assert.notNull(claimTypeMap, "Claim type map cannot be null.");
    // register a new Deserializer
    SimpleModule module = new SimpleModule();
    module.addDeserializer(Object.class, new MappedTypeDeserializer(Collections.unmodifiableMap(claimTypeMap)));
    objectMapper.registerModule(module);
    objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, failOnUnknownProperties);
}

in order to disable Jackson ObjectMapper FAIL_ON_UNKNOWN_PROPERTIES Deserialization Feature by default .

@amiriahmad72 Thanks for this! But oddly enough, it appears we were working on two nearly identical things at the same time. I opened #895 recently.

After that's merged, would you like to change this PR to work with that code change? Some cleanup was done that should enable your addition to be done simply without overloading a constructor.

@amiriahmad72 also we'll need a test case to assert the behavior works as expected (and remains working for regression purposes on future builds/releases).

Thanks alot @lhazlewood
I close this PR and reopen another one that I use your codes and also add specific test case
