JDK 9 Outreach

Dear All

I would just check that to my knowledge as regards the mobile and embedded
version of Java it is essentially now based on a JavaSE VM unless using
CLDC? (when needing to run a VM in less than about 20MB of ram).

Are there any noteworthy differences between the Java 9 targeted at Mobile
and Embedded to be aware of? I expect that at least bytecode wise it will
be the same excluding CLDC versions.
