@ancient-stone-50795: re ```Note that runtime_classpath now contains JarLibrary targets. Before we only gathered classes compiled in the repo. See https://github.com/pantsbuild/pants/issues/2359 and and attempt to fix this in https://rbcommons.com/s/twitter/r/2962```: the classpath always contained JarLibrary targets, but classes_by_target only represented source targets before.
