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.

Method Details- 
getClassContextDeprecated, 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 0is the class of the currently executing method, the element at index1is the class of that method's caller, and so on.- API Note:
- The StackWalkerclass can be used as a replacement for this method.
- Returns:
- the execution stack.
 
- 
getSecurityContextDeprecated, for removal: This API element is subject to removal in a future version.Returns anAccessControlContextwhere thecheckPermissionmethod always throws anAccessControlExceptionand thegetDomainCombinermethod always returnsnull.- 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
       AccessControlContextthat fails all permission checks. The Security Manager is no longer supported. There is no replacement for the Security Manager or this method.
- Returns:
- an AccessControlContextas specified above
