@Deprecated(since="17", forRemoval=true) public class SecurityManager extends Object
Deprecated, for removal: This API element is subject to removal in a future version.
There is no replacement for this class.
SecurityManager was originally specified to allow an application implement a security policy. It allowed an application to determine, before performing a possibly unsafe or security sensitive operation, whether the operation was being attempted in a security context that allowed the operation. This feature no longer exists.

    • SecurityManager

      public SecurityManager()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Constructs a new SecurityManager. Setting a security manager with System.setSecurityManager(SecurityManager) is not supported.

  • Method Details

    • getClassContext

      protected Class<?>[] getClassContext()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Returns the current execution stack as an array of classes.

      The length of the array is the number of methods on the execution stack. The element at index 0 is the class of the currently executing method, the element at index 1 is the class of that method's caller, and so on.

      API Note:
      The StackWalker class can be used as a replacement for this method.
      Returns:
      the execution stack.

    • getSecurityContext

      public Object getSecurityContext()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Returns an AccessControlContext where the checkPermission method always throws an AccessControlException and the getDomainCombiner method always returns null.
      API Note:
      This method originally returned a snapshot of the current calling context, which included the current thread's access control context and any limited privilege scope. This method has been changed to always return an innocuous AccessControlContext that fails all permission checks. The Security Manager is no longer supported. There is no replacement for the Security Manager or this method.
      Returns:
      an AccessControlContext as specified above
