chaokunyang opened a new issue, #2277:
URL: https://github.com/apache/fury/issues/2277
### Feature Request
Currently we don't support multi-dimensional array field serialization in
xlang meta shared mode
If we serialize such fields, we will get exception:
```java
@Test
public void testMDArrayField() {
Fory fory =
Fory.builder()
.withLanguage(Language.XLANG)
.withCodegen(false)
.withCompatibleMode(CompatibleMode.COMPATIBLE)
.build();
// TODO support multi-dimensional array serialization
fory.register(MDArrayFieldStruct.class, "example.a");
MDArrayFieldStruct s = new MDArrayFieldStruct();
s.arr = new int[][] {{1, 2}, {3, 4}};
serDeCheck(fory, s);
}
```
```java
java.lang.NullPointerException
