Attempted to create a java.lang.reflect.Proxy using the following code: require 'java'; include_class('java.lang.reflect.InvocationHandler'); include_class('java.lang.reflect.Proxy') {

x	"JProxy" };

include_class('java.lang.Runnable'); include_class('java.util.concurrent.Callable'); include_class("java.lang.reflect.Array") {

x	"JArray" };

include_class("java.lang.Class") {

x	"JClass" }

class MyRunnable < InvocationHandler def invoke(obj, name, args) puts name + " called" end end include_class('java.lang.Runnable') types = JArray.newInstance(JClass, 2); types[0] = Runnable types[1] = Callable m = MyRunnable.new r = JProxy.newProxyInstance(nil, types, m); puts r.kind_of?(Runnable) puts r.kind_of?(Callable) --------------- At JProxy.newInstance line "stack level too deep" error is thrown; searched for this string in JRuby 0.9.0 source base - found that in org.jruby.evaluator.EvaluationState class.
