aqni opened a new issue, #469:
URL: https://github.com/apache/arrow-java/issues/469
### Describe the bug, including details regarding any error messages,
version, and platform.
- version: 18.1.0
- platform: windows, jdk17
```java
@Test
void testVarbinary(){
try(RootAllocator allocator = new RootAllocator(Long.MAX_VALUE);
BigIntVector bigIntVector = new BigIntVector("test", allocator);
VarBinaryVector varBinVector = new VarBinaryVector("test",
allocator)){
bigIntVector.setNull(0);
bigIntVector.setValueCount(1);
varBinVector.setNull(0);
varBinVector.setValueCount(1);
Assertions.assertNull(bigIntVector.getObject(0));
Assertions.assertNull(varBinVector.getObject(0));
}
}
```
When I set `arrow.enable_null_check_for_get` to true, this test passes.
However, when I set `arrow.enable_null_check_for_get` to false, it failed.
```

Why does BigIntVector's getObject always return null, while VarBinary
Vector's getObject has a different behavior?
