Hi Mandy,
There could be:
public class SM1 extends SecurityManager {
@Override
public void checkMemberAccess(Class<?> clazz, int which) {...
and:
public class SM2 extends SM1 { ... // no checkMemberAccess override
now if if you take SM2.class.getDeclaredMethod("checkMemberAccess",
...) it will throw NoSuchMethodException, but the method is overriden in
SM1. So I think it's better to use what John suggested (although not
using getDeclaredMethod, but getMethod instead):
smgr.getClass().getMethod("checkMemberAccess",
...).getDeclaringClass() == SecurityManager.class
Are you concerned the overhead of an exception thrown that we should avoid?
