JupyterHub does not pass all of its environment variables to the
single-user servers, because it is likely to include hub-level credentials
that the user shouldn’t have access to. For this reason, there is a
c.Spawner.env_keep configurable that is a whitelist of environment
variables that *should* be passed down. You can specify that JAVA_HOME
should be added with:
c.Spawner.env_keep.append('JAVA_HOME')
in your jupyterhub_config.py
