使用Java 17

几天前正在工作，但突然收到此错误，尚未更改任何库版本或代码。

尝试使用

withEqualsForType(Objects::equals,XMLGregorianCalendar.class)

例如：

assertThat(actual).usingRecursiveComparison()
                                .withEqualsForType(Objects::equals,XMLGregorianCalendar.class)
                                .isEqualTo(expected);
