I get the following error in coc.nvim when opening a Scala file with nvim:

[coc.nvim] Unsupported Java version 11.0.1-testing, no functionality will work. To fix this problem, restart the server using Java 8.
[coc.nvim] Internal error.
[coc.nvim] Error output from languageserver.metals: Server initialization failed.
  Message: Internal error.
  Code: -32603

I am running Java 11 by default, but have Java 8 also installed under /usr/lib/jvm/java-8-openjdk/jre/bin/.

To reproduce, you'll have to have nvim installed and then also install vim-plug.

After then execute nvim -u metals.vim App.scala where metals.vim would contain:

call plug#begin('~/.local/share/nvim/plugged')
Plug 'neoclide/coc.nvim', {'do': { -> coc#util#install()}}
call plug#end()

Then type :messages to see the full error.

As of the 0.9.2 metals release, the metals binary built from the PKGBUILD is giving classpath errors.

Context: scalameta/metals#1948

There are a bunch of Java 8 runtime provides in AUR. It would be nice if the metals-client.sh script provided support for selecting those over the openjdk setup.
