Java code gen "incompatible types" generic list value
I am getting an error in java code gen for a map of String->String[] in java. The swagger source definition: DataMap: description: Provides a generic map of string->string additionalProperties: $ref: '#/components/schemas/StringArray' title: DataMap type: object StringArray: description: String array items: type: string title: StringArray type: array Results in java code: private Map<String, List<String>> dataMap = null; public RequestMetaData putDataMapItem(String key, List<String> dataMapItem) { if (this.dataMap == null) { this.dataMap = new HashMap<String, List>(); } this.dataMap.put(key, dataMapItem); return this; } This does not compile. It fails with error: incompatible types: HashMap<String,List> cannot be converted to Map<String,List<String>> This seems like a common definition structure. Has anyone seen this/resolved it?
