is a named permission and has no actions. There are two names currently defined. Each named permission has a corresponding public static final field which contains an instance of the named permission.The following table provides a summary description of what each named permission allows, and discusses the risks of granting code the permission.
Permission Target Name What the Permission Allows Risks of Allowing this Permission setStateManager
This allows setting the StateManager
for an instance ofPersistenceCapable
. TheStateManager
has unlimited access to get and set persistent and transactional fields of thePersistenceCapable
instance.This is dangerous in that information (possibly confidential) normally unavailable would be accessible to malicious code. getMetadata
This allows getting metadata for any PersistenceCapable
class that has registered withJDOImplHelper
.This is dangerous in that metadata information (possibly confidential) normally unavailable would be accessible to malicious code. manageMetadata
This allows managing metadata for any PersistenceCapable
class that has registered withJDOImplHelper
.This is dangerous in that metadata information (possibly confidential) normally unavailable would be manageable (modifiable) by malicious code. closePersistenceManagerFactory
This allows closing a PersistenceManagerFactory
, thereby releasing resources.This is dangerous in that resources bound to the PersistenceManagerFactory
would be releaseable by malicious code.- Version:
