Request to backport 7080038: "(ann) Serializable types in sun.reflect.annotation do not declare serialVersionUIDs" to OpenJDK 6

[Joe Darcy]

Hello.

I hereby request to approval to backport

   7080038: (ann) Serializable types in sun.reflect.annotation do not 
declare serialVersionUIDs
   http://hg.openjdk.java.net/jdk8/tl/jdk/rev/71e353aba896

to OpenJDK 6.  Some more description of the change is on

   
http://mail.openjdk.java.net/pipermail/core-libs-dev/2011-August/007490.html

The problematic fix for 6761678 "(ann) SecurityException in 
AnnotationInvocationHandler.getMemberMethods" has also present in 
OpenJDK 6 since b13:

    http://hg.openjdk.java.net/jdk6/jdk6/jdk/rev/762dd71f0008

This means that annotation objects with the correct serialVersionUIDs 
from JDK 5, Sun/Oracle's JDK 6, and OpenJDK 6 b01 through b12 have *not* 
been readable under OpenJDK 6 b13 to present (b23).

Given that to my knowledge this issue has not previously been reported, 
I'm inferring this is not a common usage pattern for annotations.

Operationally, if the fix for 7080038 is applied to in OpenJDK 6 b24, 
that will restore serial compatibility of annotations with OpenJDK 6 b01 
through b12 (and JDK 5, etc.) at the cost of creating a incompatibility 
with b13 through b23.

Since the original accidental change to the serialVersionUID went 
unnoticed, I'm hoping changing it back will also not cause any 
operational difficulties.

Cheers,

-Joe
