The context environment is set in the `ScalaShellRemoteEnvironment` to
disable creation of new environments by the user. This is done when you first
create the batch environment. Then you create the
`ScalaShellRemoteStreamEnvironment` which internally creates the
`StreamRemoteEnvironment` which fails because the context environment is
already set.
You may work around this by setting the context environment (and thereby
disabling creation of other environments) **after** you have created both of
your shell environments.
