Hi Steven, Thanks for reporting this serious issue. And yes, this is the right place to notify mesos users, which may potentially save many people a bunch of time while collecting more review comments on your PR. Also, It would be helpful to expose the risk of upgrading OpenJDK to mesos users.
Again, thanks for your PR. I will dig into it tomorrow and comment on the github pull request.
