* @summary Verify that [write/read]ObjectOverride methods get called.
|
|
28 |
* Test verifies that ALL methods to write an object can
|
|
29 |
* be overridden. Howver, the testing for reading an object
|
|
30 |
* is incomplete. Only test that readObjectOverride is called.
|
|
31 |
* An entire protocol would need to be implemented and written
|
|
32 |
* out before being able to test the input side of the API.
|
|
33 |
*
|
|
34 |
* Also, would be appropriate that this program verify
|
|
35 |
* that if SerializablePermission "enableSubclassImplamentation"
|
|
36 |
* is not in the security policy and security is enabled, that
|
|
37 |
* a security excepiton is thrown when constructing the
|
