(Updated March 12, 2014, 7:35 p.m.) Review request for Twill. Repository: twill Description ------- Implement a TwillApplication that runs bundled jars. This is to allow user programs to run without having to worry about dependency conflicts with Twill. For example, Presto uses Guava 16 whereas Twill uses Guava 13, so they can't run in the same class loader. See JarRunnerExample (in twill-examples) for example usage of BundledJarApplication (in twill-ext).

Also tested a Twill application that starts up multiple runnables that run Presto services. Thanks, Jiahua Wang
