Problem description

Getting an error when attempting to retrieve component templates from elasticsearch where the component template includes a "subobjects": false mapping. Error is:

Error deserializing co.elastic.clients.elasticsearch._types.mapping.ObjectProperty: co.elastic.clients.json.UnexpectedJsonEventException: Unexpected JSON event 'VALUE_FALSE' instead of '[KEY_NAME, VALUE_STRING]' (JSON path: component_templates[0].component_template.template.mappings.properties.doc.subobjects)

This seems to be the same issue for subobjects as previously occurred for Refresh and DynamicMapping (see: https://github.com/elastic/elasticsearch-java/issues/139 and https://github.com/elastic/elasticsearch-java/pull/275).

To reproduce:

String templates = """
{
  "component_templates": [
    {
	  "name": "test-template",
	  "component_template": {
	    "template": {
		  "mappings": {
		    "properties": {
			  "document": {
			    "subobjects": false,
				"properties": {
				  "body.size": {
				    "type": "integer"
				  }
				}
			  }
			}
		  }
		}
	  }
	}
  ]
}
"""

new GetComponentTemplateResponse.Builder().withJson(new StringReader(templates));
