AccessibleObject canAccess is new in 9 to test if a reflected object is 
accessible. Another new API is trySetAccessible to avoid using 
exceptions for control flow.

To your example then if setAccessible succeeds in suppressing access to 
a JDK internal member then you'll get a warning if it's the first 
illegal access. If setAccessible fails then you'll 
InaccessibleObjectException will be thrown as it does not, there will be 
no warning.
