scala@2.11 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have scala@2.11 first in your PATH run:

For the system Java wrappers to find this JDK, symlink it with
sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk
openjdk is keg-only, which means it was not symlinked into /usr/local,
because it shadows the macOS `java` wrapper.
If you need to have openjdk first in your PATH run:
echo'export PATH="/usr/local/opt/openjdk/bin:$PATH"' >> /Users/aoki.makoto/.bash_profile
For compilers to find openjdk you may need to set:
export CPPFLAGS="-I/usr/local/opt/openjdk/include"
