JDK 6 to JDK 8, it was been a warning at compile time to use JDK 
internal APIs. This changed to be a compile-time error in JDK 9, and for 
code compiled to older releases, an error at run-time since JDK 16.

In the case of sun.security.action.GetPropertyAction then this was for 
the security manager case that is gone since JDK 24. So now needed now. 
There was a never a good reason to use this sun.* class directly as it 
just used AccessController.doPrivileged to invoke System.getProperty. So 
should be easy to replace the usage.
