> Hi all,
> The method `Types.isCastable` uses method `Types.areDisjoint` to do some check. But `Types.isCastable` doesn't check the type of the parameter before invoking method `Types.areDisjoint`. This patch adds the corresponding check and add a test case.
> Thank you for taking the time to review.
> Best Regards.
