A DESCRIPTION OF THE PROBLEM :
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.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached Java and Jasm program. Might need https://github.com/openjdk/asmtools/pull/46 to compile successfully.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The program completes successfully.
ACTUAL -
The program throws `java.lang.AssertionError`:
```
