JMH error Annotation generator had thrown the exception. java.lang.ClassCastException

[Vipin Sharma]

Hi,
I am getting an error while compiling code, the error is: Annotation
generator had thrown the exception. java.lang.ClassCastException

In this benchmark, I have removed most of the code just enough to
reproduce this problem.
Seems this is because of test method signature.

package org.sample;import org.openjdk.jmh.annotations.Benchmark;import
java.util.EnumSet;public class MyBenchmark {
    @Benchmark
    public static <E extends Enum<E>> EnumSet<E> test(E param) {
        return null;
    }}

I have tried this on JDK8, 13 and 14.Using JMH (1.23)
OS Ubuntu.

Is there anything wrong with the benchmark code?
