Disallow ENV and ENV_JAVA in JRuby

Question

Is it possible to disallow the use of ENV and ENV_JAVA in JRuby? I allow user supplied ruby code to run in servers, and I believe allowing them to use ENV and ENV_JAVA is not a very good idea.

I was able to disallow the use of System.get/setProperty() using Java's Security Manager, but I haven't had much success in this case.

Thanks in advance!

This should do the trick:

class Object
  remove_const :ENV
  remove_const :ENV_JAVA
end
