# TODO add test, see about packaging jtreg and using it here
# TODO see about building with OpenJDK9
# TODO add javazi
# TODO when IcedTea provides it, package icedtea-web and add it as optdepends
# TODO package OpenJFX for OpenJDK9 and add it as optdepends

## EXPLORATIONS
# TODO extract a jmods package from jdk9-openjdk?
# TODO extract a jdk-headless package?
#      Now that `jconsole` and `policytool` belong to JDK, one could extract
#      these to their own package.
#      FYI, `jdk8-openjdk` already depends on `jre8-openjdk` and not `jre8-openjdk-headless`
