If you have a rails app that accesses ARGV, the constant containing command-line
parameters, it will fail under the grizzly Rails support. This is because the
JRuby runtime needs to be initialized with ARGV. We have not yet decided to make
JRuby automatically prepare ARGV, since it generally needs to come from outside
the runtime; but it seems like this should be added to the connector so that the
runtimes are fully functional. Even an empty list would be sufficient.
