The Glassfish Primitive Function Library (PFL) contains an interesting use case for setAccessible: an enhanced object-to-string capability. Now, in an ideal world, this shouldn’t be needed, as each object provides an adequate toString() method; however, it is not uncommon while trying to diagnose a problem, to need to see the actual state of objects, as represented by their fields, as the toString() function often doesn’t show everything. This is especially important to diagnose problems in production, where one could ask a customer to enable a debug flag. Until now, this was restricted only by the security manager. What can we do to keep such a capability in JDK9?
you have to declare all the module and the packages you want to access as open. On the command line this is done by using --add-opens. For example --add-opens java.base to open all classes in the java.base module. At runtime you have to use the Module and Layer APIs to realize this...
