Alessandro Solimando commented on CALCITE-7398:
-----------------------------------------------
I usually read the "affects version" field as the first known version where the
problem appeared, and if the issue is open, for me it's still an issue for the
current version (which you have confirmed, good thing to do)
> 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: 1.38.0
> 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}
