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
