/**

|
* This class is for Serializable permissions. A SerializablePermission
|
|
* contains a name (also referred to as a "target name") but
|
|
* no actions list; you either have the named permission
|
|
* or you don't.
|
|
*
|
|
* <P>
|
|
* The target name is the name of the Serializable permission (see below).
|
|
*
|
|
* <P>
|
|
* The following table lists all the possible SerializablePermission target names,
|
|
* and for each provides a description of what the permission allows
|
|
* and a discussion of the risks of granting code the permission.

* deserialize classes in a purposefully malfeasant manner. For example,
|
|
* during serialization, malicious code can use this to

* purposefully store confidential private field data in a way easily accessible
|
|
