10:50 <Thijsc> Hi All. I'm looking for some guidance on how to call things in a Rails app from Java land. We've been heavily using Kafka, I'm trying to get an open source library together that acts as a proxy between the Kafka Connect library and Ruby. I have the basics working by copying some stuff from Redstorm. So I receive data from Kafka on the Ruby side.

10:50 <Thijsc> This all works fine mostly using ScriptingContainer

10:51 <Thijsc> What I'm stuck on is coming up with a good way to load in our Rails app. I can make a war using warble which works well. I can't seem to find a proper way to add that Jar to the classpath in such a way that I can initialize the Rails app and call stuff in it using ScriptingContainer.

10:52 <Thijsc> Any pointers on a way to do this?

11:05 <Thijsc> Or maybe some other project uses this approach?

18:20 <hobodave> Hey guys. I'm not clear on whether or not I should be using -Xcompile.invokedynamic=true with jruby-9.1.7.0 running on Java 1.8.0_121-b13

18:20 <hobodave> https://github.com/jruby/jruby/wiki/PerformanceTuning - this says it is enabled by default on JDK 8 builds, but jruby --properties says it defaults to false

18:20 <hobodave> which is it?

18:21 <enebo> hobodave: that is out of date.

18:21 <hobodave> which?

18:21 <enebo> hobodave: that flag is off by default

18:21 <enebo> hobodave: ...but...

18:22 <enebo> hobodave: we do use invokedynamic for many things internally now by default but not all the things

18:22 <enebo> hobodave: so enabling that might give you a good speed bump or not depending on your code

18:22 <hobodave> Is the current recommendation to try enabling it?

18:22 <hobodave> gotcha

18:22 <enebo> hobodave: we disabled it as a default not because it did not run well but because it tended to make warmup in Rails take too long

18:23 <enebo> hobodave: but your mileage may vary...not everyone was complaining...just enough to ratchet it back a bit

18:23 <enebo> I will update the document

18:23 <enebo> hobodave: definitely try it enabled though and see how things go

18:24 <hobodave> Great, is there specific patterns I should pay attention to that might not perform well?

18:24 <hobodave> *are

18:25 <enebo> hobodave: in general everything will be faster or the same speed but if it warmup appears to take longer then you will need to decide if that is a problem or not

18:26 <hobodave> I really appreciate your help enebo. WOuld you recommend a resource to read about what invokedynamic really is? My java-fu is weak

18:27 <enebo> hobodave: headius has written several blogs showing how it can be used and how JRuby uses it.

18:27 <hobodave> thank you!

18:27 <enebo> hobodave: some are several years old now but the gist is there. It is fairly low-level in explaining how implementations can use it

20:38 <hobodave> I just noticed that jruby 9.1.8.0 no longer provides lib/jruby-truffle.jar -- I didn't use this, but I'm wondering what happened to it
