'is' not @JsonIgnore-d

With Lombok 1.18.12 and Jackson 2.11.0, this POJO:

@Data @NoArgsConstructor
private static class MyPojo {
	private Long id = 1L;
	private boolean isGood = true;
	@JsonIgnore
	private boolean isIgnored = false;

}

does not ignore the isIgnored field so the test fails:

@Test
public void serializePojo() throws IOException {
    ObjectMapper objectMapper = new ObjectMapper();
    MyPojo pojo = new MyPojo();
    String actualJson = objectMapper.writeValueAsString(pojo);
    String expectedJson = "{\"id\":1,\"good\":true}";

    assertThat(actualJson).asString().isEqualToIgnoringWhitespace(expectedJson);
}

because the actual JSON is:

JSON{"id":1,"ignored":false,"good":true}

One solution is to add @JsonIgnore to an explicit getter:

@Data @NoArgsConstructor
private static class MyPojo {
	private Long id = 1L;
	private boolean isGood = true;
	private boolean isIgnored = true;

	@JsonIgnore
	public boolean isIgnored() {
		return isIgnored;
	}

}

A work-around is to avoid the (common) is prefix on boolean properties:

@Data @NoArgsConstructor
private static class MyPojo {
	private Long id = 1L;
	private boolean isGood = true;
    @JsonIgnore
	private boolean ignored = true;

}
