### Describe the bug, including details regarding any error messages,
version, and platform.
added test case to TestStructVector:
```java
@Test
public void testStructVectorTransferPairWithNullType() {
Field uuidField = new Field("null",
FieldType.nullable(ArrowType.Null.INSTANCE), null);
Field structField =
new Field("struct", FieldType.nullable(new ArrowType.Struct()),
List.of(uuidField));
try(StructVector s1 = (StructVector)
structField.createVector(allocator)) {
NullVector nullVector =
s1.addOrGet("null",
FieldType.nullable(ArrowType.Null.INSTANCE), NullVector.class);
s1.setValueCount(1);
nullVector.setNull(0);
s1.setIndexDefined(0);
TransferPair tp = s1.getTransferPair(structField, allocator);
try (StructVector toVector = (StructVector) tp.getTo()) {
assertEquals(s1.getField(), toVector.getField());
}
}
}
```
got this:
```
java.lang.UnsupportedOperationException: Unknown type: NULL

```
expected: similar result to `testStructVectorTransferPairWithExtensionType`
Cheers!
