Examples of org.jruby.util.OneShotClassLoader

org.jruby.util.OneShotClassLoader
Represents a class loader designed to load exactly one class.

                interfacesHashCode = 31 * interfacesHashCode + runtime.getProc().hashCode();
                classLoader = runtime.getJRubyClassLoader();
            } else {
                // normal new class implementing interfaces
                interfacesHashCode = 31 * interfacesHashCode + wrapper.getMetaClass().getRealClass().hashCode();
                classLoader = new OneShotClassLoader(runtime.getJRubyClassLoader());
            }
            String implClassName = "org.jruby.gen.InterfaceImpl" + Math.abs(interfacesHashCode);
            Class proxyImplClass;
            try {
                proxyImplClass = Class.forName(implClassName, true, runtime.getJRubyClassLoader());
