The Ruby object represents the top-level of a JRuby "instance" in a given VM. JRuby supports spawning multiple instances in the same JVM. Generally, objects created under these instances are tied to a given runtime, for such details as identity and type, because multiple Ruby instances means there are multiple instances of each class. This means that in multi-runtime mode (or really, multi-VM mode, where each JRuby instance is a ruby "VM"), objects generally can't be transported across runtimes without marshaling. This class roots everything that makes the JRuby runtime function, and provides a number of utility methods for constructing global types and accessing global runtime structures.

        Ruby runtime = context.getRuntime();


        // not allowed for existing Java interface modules
        if (module.getInstanceVariables().fastHasInstanceVariable("@java_class") &&
                module.getInstanceVariables().fastGetInstanceVariable("@java_class").isTrue()) {
            throw runtime.newTypeError("can not add Java interface to existing Java interface");
        }
        
        // To turn a module into an "interface collection" we add a class instance
        // variable to hold the list of interfaces, and modify append_features
        // for this module to call append_features on each of those interfaces as
