Summary: The Security Manager has not been the primary means of securing client-side Java code for many years, it has rarely been used to secure server-side code, and it is costly to maintain. We therefore deprecated it for removal in Java 17 via JEP 411 (2021). As the next step toward removing the Security Manager, we will revise the Java Platform specification so that developers cannot enable it and other Platform classes do not refer to it. This change will have no impact on the vast majority of applications, libraries, and tools. We will remove the Security Manager API in a future release. - Mark
