Project proposal: s390x port

[dalibor topic]

Hi David,

thank you for your proposal. As usual, I have a few questions in order 
to better understand the Project being proposed.

I noticed that you sent the proposal from a gmail address, while a 
person of the same name seems to work [0] at IBM, who happen to produce 
s390x architecture machines. Do you happen to be the same person by 
chance? If so, would you be contributing to this Project on behalf of 
IBM, or on your own behalf?

Could you elaborate a bit on the nature of the development work:

  * Who would be in the initial set of the Project's Committers?
  * Would you have Reviewers on the Project?
  * Would you be starting from scratch within the new OpenJDK Project, 
or are you looking at bringing an already existing, internal port in?
  * In the latter case, does the code you'd like to contribute to the 
port have any third party dependencies?
  * In the former case, are you aware of the Open Mainframe Project, 
which seems to intend to produce a JIT for OpenJDK, as well? [1]
  * Which JDK release would you plan to target initially?

OK. I assume that C1 is not something your port needs, or is it 
something you'll consider for a later iteration?

That issue is now https://bugs.openjdk.java.net/browse/JDK-8156104 . 
It's also been marked as closed, as there is no need to submit issues to 
create new Projects. The process is documented at 
http://openjdk.java.net/projects/#new-project .

When a new Project is created, its Project Lead, Committers, Reviewers 
and Authors get write access to the JDK Bug System within their Project.

cheers,
