Further, you are provided with file contents of several files in the repository that contain relevant code (in <code> brackets). It may be necessary to use code from third party dependencies or files not contained in the attached documents however. Your task is to identify the issue and implement a test case that verifies a proposed solution to this issue. More details at the end of this text.\n<issue>\n      ### Search before asking\n\n- [X] I searched in the [issues](https://github.com/FasterXML/jackson-databind/issues) and found nothing similar.\n\n### Describe the bug\n\nWhen using a mapper with a `PropertyNamingStrategy` configured, the following exception is thrown when trying to deserialize an enum that contains a field with the same name as one of the enum constants:\n\n```\n\ncom.fasterxml.jackson.databind.exc.InvalidDefinitionException: Multiple fields representing property \"foo\": tech.picnic.config.util.EnumDeserializationTest$SomeEnum#FOO vs tech.picnic.config.util.EnumDeserializationTest$SomeEnum#foo\n at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); line: 1, column: 1]\n    at com.fasterxml.jackson.databind.exc.InvalidDefinitionException.from(InvalidDefinitionException.java:67)\n    at com.fasterxml.jackson.databind.DeserializationContext.reportBadDefinition(DeserializationContext.java:1887)\n    at com.fasterxml.jackson.databind.deser.DeserializerCache._createAndCache2(DeserializerCache.java:289)\n    at com.fasterxml.jackson.databind.deser.DeserializerCache._createAndCacheValueDeserializer(DeserializerCache.java:265)\n    at com.fasterxml.jackson.databind.deser.DeserializerCache.findValueDeserializer(DeserializerCache.java:163)\n[...]\n```\n\nIt seems that [now enum constants are also considered fields](https://github.com/FasterXML/jackson-databind/blob/4afceacea960d5339b796feae5cfbc2ed39e2033/src/main/java/com/fasterxml/jackson/databind/introspect/AnnotatedFieldCollector.java#L127-L130), which can clash with an enum's field when they are renamed. See also https://github.com/FasterXML/jackson-databind/commit/2134584da8e43853e1f982d01b05359927680b9c.\n\n### Version Information\n\n2.16.1\n\n### Reproduction\n\n\n```java\n  @Test\n  void shouldDeserialize() throws IOException {\n    var objectMapper =\n            JsonMapper.builder()\n              .propertyNamingStrategy(PropertyNamingStrategies.SNAKE_CASE)\n              .build();\n    assertThat(objectMapper.readValue(\"\\\"FOO\\\"\", SomeEnum.class))\n            .isEqualTo(SomeEnum.FOO);\n  }\n\n  enum SomeEnum {\n    FOO(0);\n\n    public final int foo;\n\n    SomeEnum(int foo) {\n      this.foo = foo;\n    }\n  }\n``` \n\n\n### Expected behavior\n\nSimilar to Jackson 2.15.3, I would expect this enum to be deserializable given we don't specify any mixins on the constants.\n\n### Additional context\n\nThe reproduction case above has a public field, but the issue is also apparent if the field is private and the following visibility is configured:\n\n```java\n  .visibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.NONE)\n  .visibility(PropertyAccessor.CREATOR, JsonAutoDetect.Visibility.ANY)\n  .visibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)\n```\n\n</issue>\nPlease generate test cases that check whether an implemented solution resolves the issue of the user (at the top, within <issue/> brackets).\nYou may apply changes to several files.\nApply as much reasoning as you please and see necessary.\nMake sure to implement only test cases and don't try to fix the issue itself.\nYou are not allowed to read git history.\n", "memory": "8192m", "runnable": false, "difficulty": "hard", "language": "", "cpus": "", "instruction_truncated": false, "category": "test-generation", "compose": false, "has_solution": true, "oracle": null, "docker_image": "", "taskset": "devopsgym", "tags": ["test-generation", "devops-bench"]}, "runs": []}
