There's an issue pushing Phusion Passenger 4.0.16 to Heroku.

I talked with @headius and turning off indy fixed the issue.

Maybe you could check the java runtime version and only enable indy if it's 1.8+ I'm trying to test it with my app but I can't seem to force my slug to use 1.8.

Edit: Also this fix will hurt performance for Puma/JRuby users. Maybe it requires a bit more investigation.

@rwilliams you can opt in by setting JRUBY_OPTS as a config var, but after talking with @headius, we should enable it by default only after 7u40. We're currently on 7u30 on cedar.

Edit: 7u40 is supposed to fix the remaining indy bugs. :)

@hone Makes sense. Thanks
