Examples of java.io.SerializablePermission

java.io.SerializablePermission
SerializablePermission objects represent permission to access unsafe serialization operations. The name of the permission should be one of:

enableSubclassImplementation

Subclasses can override serialization behavior

enableSubstitution

Object substitution can be enabled

@see ObjectStreamConstants
