JDK11 throw exception: unable to make protected java.lang.Class jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass

Hi team, When I upgrade jdk from 8 to 11, I got a new exception with powermock.

My test code look like below:

@RunWith(PowerMockRunner.class)
@PowerMockIgnore({"jdk.internal.loader.*"})
@SuppressStaticInitializationFor("org.apache.dolphinscheduler.spi.utils.PropertyUtils,")
@PrepareForTest(value = {UserGroupInformation.class, CommonUtils.class})
public class CommonUtilsTest {

}
