You can add an empty class to make 'master' work with 'morty':

https://github.com/Angstrom-distribution/meta-angstrom/commit/2eca0f1c932f098eb7fd877c5b00225408b2e42d

And I had to do this to make it build:

https://github.com/Angstrom-distribution/meta-angstrom/blob/709abee819ee349dab873f6abb02c404b2c65331/recipes-tweaks/ecj/ecj-initial-native.bbappend

With this I can build 'openjre-8' on debian and fedora hosts for armv7 and
x86_64. It even runs jenkins, but it used 4x the amount of memory openjdk-7
did :(
