Better JEP 411 News: Correct Deprecation of SecurityManager
"We have updated the JEP with a few changes to the "Issue Warnings" section , summarized as follows: If the Java runtime is started without setting the system property 'java.security.manager' then a custom Security Manager can be installed dynamically by calling System::setSecurityManager, just as in Java 16. No UnsupportedOperationException will be thrown. This call will, however, issue a warning message explaining that the Security Manager is deprecated and will be removed in a future release. We plan to change the default value of the 'java.security.manager' system property to "disallow" in the next release, i.e., Java 18. That will cause System::setSecurityManager to throw an UnsupportedOperationException in Java 18. With these changes, the process of deprecating and eventually removing the Security Manager will be consistent with our treatment of past breaking changes such as, e.g., the strong encapsulation of internal APIs. Maintainers of libraries and applications will be given fair warning before any existing code is broken."
