Stream API - how to build -

[Eric Caspole]

Hi Juanjo,
The JDK 8 code in the Sumatra hg repo is really old and actually we have 
not been using it yet.

If you could explain a little more about what you want to do we can see 
if our modified Stream API at:

  http://cr.openjdk.java.net/~ecaspole/sumatrajdk.02/webrev/

will work for you. Note this webrev is probably bit rot since it is from 
last July. I will do my best to update it tomorrow so it works with the 
JDK 8 tip, which is:

  http://hg.openjdk.java.net/jdk8/jdk8/

Then you check out and build Graal, and the patch connects Graal to the 
JDK Stream offload.
We are happy to welcome more Sumatra developers.
Regards,
Eric
