Rspecs stubbed return values lost after Array.#to_java

Ruby JRuby

Trying to upgrade from jruby-1.1.2 to the 1.1.6RC1 I’m running into
problems with stubbed behavior(rspec) on java methods being lost
after [].to_java. See below.

require ‘MyClass’

describe “[].to_java” do

Works in jruby-1.1.2 and jruby-1.1.3 but broken in jruby > 1.1.4

it “should behave consistently with stubbed and real return
values” do
real = Java::MyClass.new
stubbed = Java::MyClass.new

 real.stringProperty = 'hello'
 stubbed.stub!(:stringProperty).and_return'hello'

 java_array = [real].to_java(Java::MyClass)
 real.stringProperty.should == 'hello'
 java_array[0].stringProperty.should == 'hello'

 java_array = [stubbed].to_java(Java::MyClass)
 stubbed.stringProperty.should == 'hello'
 java_array[0].stringProperty.should == 'hello' #fails here

end

end

//MyClass.java
public class MyClass {
public String stringProperty;
}

Actually it looks like this is more about to_java is returning a java
array with entirely different objects.

this works up in 1.1.2 and 1.1.3 but fails with jruby >= 1.1.4

it “should do shallow copies” do
o = Java::MyClass.new

 java_array = [o].to_java(Java::MyClass)

 o.equal?(java_array[0]).should be_true

end
