Class.newInstance performance JDK11 vs JDK8

We are seeing a performance degradation on JDK11 with Class.newInstance() as compared to JDK8.

For quick check I executed below class on both JDK11 and JDK8. Execution time is ~25ms vs ~14ms in JDK11 and JDK8 resectively.

Is this a known issue or any workaround?

public class PerformanceTest {

    public PerformanceTest() {

    }

    public static void main(String[] args) {

        long l = System.currentTimeMillis();

        for (int i = 0; i < 100000; i++) {

            try {

                PerformanceTest.class.newInstance();

            } catch (InstantiationException e) {

                e.printStackTrace();

            } catch (IllegalAccessException e) {

                e.printStackTrace();

            }

        }

        System.out.println("time taken = " + (System.currentTimeMillis() - l) + "ms");

    }

}
