我收到java.lang.IllegalArgumentException：以下程序的非法團體參考public static void main(String args[]) {    String finalQueryString = "TAC: (dash_board or platform* or interfac* or portal* or app or (computer w5 (application or instruction*)) or program or software) and (educat* or ((work* or workforce or employment or job or career) w5 (skill or profile or expertise or abilit* or proficien* or competence or experience)) or train* or certifi*) and ((rank* or scor* or grad* or rate* or rating) w9 (educat* or skill or profile or expertise or abilit* or proficien* or competence or train* or certifi*)) and AC: (G06Q10/063112 or G06Q10/1053$)   ";    System.out.println(String.format("(%s)", finalQueryString.trim()));    String matchedValue = "L12";    System.out.println(String.format("((?<!\\w)%s(?!\\w))", matchedValue));    String parsedQuery = "SC:L12 not SC:L11";    parsedQuery = parsedQuery.replaceAll(String.format("((?<!\\w)%s(?!\\w))", matchedValue), String.format("(%s)", finalQueryString.trim()));    System.out.println(parsedQuery);}在 parsedQuery Line 中，我收到非法組引用異常，我無法弄清楚為什么會發生這種情況，有人可以弄清楚嗎？
