---------------------------
Affects Version/s: 1.41.0
(was: 1.38.0)
> Incorrect int cast in VariantNonNull#cast for BIGINT
> ----------------------------------------------------
>
> Key: CALCITE-7398
> URL: https://issues.apache.org/jira/browse/CALCITE-7398
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.41.0
> Reporter: heng qian
> Priority: Major
> Labels: pull-request-available
>
> In `VariantNonNull.java`, the `cast()` method has a bug in the `BIGINT` case
> at line 289:
> {code:java}
> case BIGINT: {
> long l = (int) value; // Bug: should be (long) value
> ...
> } {code}
> 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.
> {code:java}
> java.lang.ClassCastException: class java.lang.Long cannot be cast to class
> java.lang.Integer (java.lang.Long and java.lang.Integer are in module
> java.base of loader 'bootstrap'){code}
