heng qian updated CALCITE-7398:
-------------------------------
Description:
In `VariantNonNull.java`, the `cast()` method has a bug in the `BIGINT` case at
line 289:
```java
case BIGINT:
{ long l = (int) value; // Bug: should be (long) value
... }
```
The value field for BIGINT type is stored as Long (verified by the
constructor's assertion assert value instanceof Long). However, the code
incorrectly casts it to int before assigning to the long variable.
This causes a variant value with BIGINT runtime type to be null, since the
cast function throws exception in this place.
```
class java.lang.Long cannot be cast to class java.lang.Integer
```
