Further, you are provided with file contents of several files in the repository that contain relevant code (in <code> brackets).

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      **Describe the bug**\n\nWhen trying to deserialise an empty JSON string as `java.util.Locale`, the resulting value is `NULL`, when ACCEPT_EMPTY_STRING_AS_NULL_OBJECT is set to `true`.\nMy expectation was that the empty string would be converted to `Locale.ROOT`.\n\n**Version information**\n2.13.5\n\n**To Reproduce**\n\nThe following test fails:\n\n```java\nclass JsonDeserializationTest\n{\n    @Test\n    void testDeserializeRootLocale() throws JsonProcessingException\n    {\n        ObjectMapper objectMapper = new ObjectMapper();\n        objectMapper.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);\n\n        assertEquals(Locale.ROOT, objectMapper.readValue(\"\\\"\\\"\", Locale.class));\n    }\n}\n```\n\nWhen looking at the current source code at https://github.com/FasterXML/jackson-databind/blob/2.16/src/main/java/com/fasterxml/jackson/databind/cfg/CoercionConfigs.java#L241\nIt looks like `CoercionAction.TryConvert` should be returned in this case.\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": []}
