Usage instructions
------------------

You should define at least the following variables in a distro include file or local.conf

# Possible provider: cacao-initial-native and jamvm-initial-native
PREFERRED_PROVIDER_virtual/java-initial-native = "cacao-initial-native"

# Possible provider: cacao-native and jamvm-native
PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"

# Optional since there is only one provider for now
PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native"

Simply rely on openjdk-7-jre, openjdk-7, openjdk-8 or openjre-8.

For conf/bblayers.conf you have to add

BBLAYERS ?= " \
   ...
  path_to_source/meta-openembedded/meta-oe \
  path_to_source/sources/meta-java \
  "

Please note that libstdc++ static is needed on your host to compile icedtea7-native
(install libstdc++-static on a Fedora).

For debian-based distributions you need the libstdc++6-$compilerversion-dev package.
