I got a problem about enum type

[haonit]

my code is :

Java.perform(function(){
   var urlConn = Java.use('java.net.URL');
   var proxy = Java.use('java.net.Proxy');
   var isa = Java.use('java.net.InetSocketAddress');
   var iproxy = proxy.$new(proxy._Type.HTTP, isa.$new('10.20.10.141',8080));
   urlConn.openConnection.overload('java.net.Proxy').implementation = function(p){
       console.log("called openConnection");
       var retval = this.openConnecttion(iproxy);
       return retval;
   }

})

when I hook the app; I got this:

TypeError: cannot read property 'HTTP' of undefined

I test it works like this.

var proxy = Java.use("java.net.Proxy");
var proxyType = Java.use('java.net.Proxy$Type');
var inetSocketAddress = Java.use("java.net.InetSocketAddress");
var inetSocketAddressInstance = inetSocketAddress.$new("192.168.8.33", 8888);
var proxyInstance = proxy.$new(proxyType.valueOf("HTTP"), inetSocketAddressInstance);
