public final class JDIPermission extends BasicPermission
The JDIPermission class represents access rights to the VirtualMachineManager. This is the permission which the SecurityManager will check when code that is running with a SecurityManager requests access to the VirtualMachineManager, as defined in the Java Debug Interface (JDI) for the Java platform.
A JDIPermission object contains a name (also referred to as a "target name") but no actions list; you either have the named permission or you don't.
The following table provides a summary description of what the permission allows, and discusses the risks of granting code the permission.
| Permission Target Name | What the Permission Allows | Risks of Allowing this Permission |
|---|---|---|
| virtualMachineManager | Ability to inspect and modify the JDI objects in the VirtualMachineManager | This allows an attacker to control the VirtualMachineManager and cause the system to misbehave. |
Programmers do not normally create JDIPermission objects directly. Instead they are created by the security policy code based on reading the security policy file.
