Arch Linux

Description:

Latest ammonite package is not running when combined with jdk11-openjdk. The following error occurs when starting ammonite and doing any interaction with the repl (i.e. pressing new line)

java.lang.UnsupportedClassVersionError: io/github/retronym/java9rtexport/Export has been compiled by a more recent version of the Java Runtime (class file version 57.0), this version of the Java Runtime only recognizes class file versions up to 55.0

Note that its likely that this bug is specific to Archlinux and how it configures Java since ammonite basically fails to work on startup (and so if it was a generic upstream bug a lot more people would complain about it).

Additional info:
* ammonite 2.1.4-1
* jdk11-openjdk
* upstream bug is here https://github.com/lihaoyi/Ammonite/issues/1107

Steps to reproduce: Install ammonite and then install jdk11-openjdk
