Hello Ivan,

Do you build OpenJDK? Just wondering if you are able to build the 
jigsaw/m2 forest? The jigsaw/m2 forest is where we are currently working 
to modularize the structure of the binary images created by build. The 
modular image was cited in JEP 200 and will have its own JEP shortly. 
There is lots to talk about there as changing the layout of the binary 
images is going to be somewhat disruptive. We know there is a lot of 
code and scripts that depend on the current layout or directly access 
rt.jar or tools.jar. In case it's not clear then the proposal is to do 
away with rt.jar and tools.jar and introduce a new container format for 
the modules, classes and resources that are linked into the image. This 
new container format will change over time and is not intended to be 
accessed directly. We hope to make EA builds available soon after the 
JEP is published so that's another way to try this out for those that 
don't build OpenJDK.

-Alan.
