If I use a Java class to create Ruby objects, they cannot be sent over DRb. i.e:

package com.kylemaxwell.development;
import org.jruby.*;
import java.util.*;
public class Fu
{
  public static RubyHash rubyHashPlease()
  {
    Ruby jruby = Ruby.getDefaultInstance();
    HashMap map = new HashMap();
    map.put(
       RubyString.newUnicodeString(jruby,  "foo"), 
      RubyString.newUnicodeString(jruby,  "bar")
    );
    return new RubyHash(jruby, map, new RubyNil(jruby));
  }
}

# jirb
 > require "java"
=> true
 > Fu = com.kylemaxwell.development.Fu
=> Java::ComKylemaxwellDevelopment::Fu
 > Fu.ruby_hash_please
=> {"foo"=>"bar"}
 > Fu.ruby_hash_please
=> {"foo"=>"bar"}
 > Marshal::dump _
=> "\004\010{\006\"\010foo\"\010bar"
 > Marshal::load _
=> {"foo"=>"bar"}
 > require 'drb'
=> true
 > DRb.start_service nil, Fu
=> #<DRb::DRbServer:0x9...
 > DRb.uri
=> "druby://kyle.wan:59476"

# other window...
 > require 'drb'
=> true
 > DRb.start_service

>> Fu = DRbObject.new nil, "druby://kyle.wan:59476"
=> #<DRb::DRbObject:0x65bd14 @ref=nil, @uri="druby://kyle.wan:59476">
 > Fu.ruby_hash_please
