Parsing case insensetive fields

[DmRomantsov]

It's works by using jackson-databind version 2.5.0, but doesn't work in 2.6.3

private final String json = "{\"ErrorCode\":2,\"DebugMessage\":\"Signature not valid!\"}";

@Test
public void testParsing() throws Exception {
    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);
    mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    BaseResponse response = mapper.readValue(json, BaseResponse.class);
    Assert.assertEquals(response.getDebugMessage(), "Signature not valid!");
    Assert.assertEquals(response.getErrorCode(), 2);
}

static class BaseResponse {

    protected int errorCode;
    protected String debugMessage;

    public String getDebugMessage() {
        return debugMessage;
    }

    public void setDebugMessage(String debugMessage) {
        this.debugMessage = debugMessage;
    }

    public int getErrorCode() {
        return errorCode;
    }

    public void setErrorCode(int errorCode) {
        this.errorCode = errorCode;
    }
}

StackTrace:
java.util.NoSuchElementException: No entry 'debugMessage' found, can't replace

Thank you for reporting this -- fixed in upcoming 2.6.4 release.

I have same error. And this is simple json that can't deserialize.
My POJO is

@TorosyanV could you please file a new issue for this? Since the original problem (the specific case) was resolved, as per unit test, this may well be related (assuming you are using version 2.6.4), but the underlying fix is different. You can add a reference to this issue in the new one.
