To see the issue then you'll need a build of jdk8/tl rather than 
jdk8/jdk8 as the changes haven't been integrated into the master yet. We 
really need to get to the point where the entire JDK is built with 
-Xlint:serial -Werror as it's too easy to inadvertently change the SUID. 
Aside from a few specified tests, the tests in the jdk repository don't 
test serialization compatibility.
