Ubuntu 16.04 では以下をインストールしましたscala:
$ls ~/Binary/scala-2.11.8
bin doc lib man
$grep -A 2 SCALA ~/.bashrc
SCALA=~/Binary/scala-2.11.8
SBT=~/Binary/sbt
export PATH=$PATH:$SCALA/bin:$SBT/bin
インストールするとopenjdk8、scalaREPL を開くときに失敗します。
$javac -version
javac 1.8.0_91
$
$scala

** For the old behavior pass -usejavacp to scala, or if using a Settings
** object programmatically, settings.usejavacp.value = true.
