Thanks Christian for pushing all of those.

However, I just noticed that the JDK part for my very first zero/shark
related change is still not in the repos :-)

http://cr.openjdk.java.net/~rkennke/shark/webrev-jdk-00/

As far as I can see there is now way for me to push it (even though you
approved it). Could you please push that as well, to make things
complete?

Best regards,
