Re: putting symbols into Environment

[Sonny To <son dot c dot to at gmail dot com>]

oddly the fix is to first put into the environment before creating the repl

val env = Environment.getCurrent()
env.put(Symbol.valueOf("context"), applicationContext)
TelnetRepl.serve(lang, client)

the symbol "context" is now available in the repl
