Thank you for the example.
Yes, I'm working on a helpful message and was thinking to use the 
Reflection method:
 IllegalAccessException newIllegalAccessException(Class<?> currentClass,
                                                  Class<?> memberClass,
                                                  Class<?> targetClass,
                                                  int modifiers);
m.canAccess(null) will tell you if the premain method is accessible. If 
it returns false then you can thrwo IAE with a useful message.

If we call setAccessible(true) then canAccess will return true.

If we don't call setAccessible(true) then canAccess will return false 
due to the problem Serguei reported.
