When `Class.getEnumConstants()` is called on a bad enum class where `values()` is an instance method, or returns a non‑array, then it throws `NullPointerException` or `ClassCastException` respectively.
This patch fixes `Class.getEnumConstants()` method to handle above mentioned bad enums and adds relevant tests. Please review.
