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.

getClassContextback to summary
protected Class<?>[] getClassContext()

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:Class<?>[]

the execution stack.

getSecurityContextback to summary
public Object getSecurityContext()

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:Object

an AccessControlContext as specified above

getThreadGroupback to summary
