expect.that() error comparing null to String

[Google Code Exporter]

What steps will reproduce the problem?
1. Compile attached code
2. Run with JUnit4 (note @RunWith annotation)
3. Notice Specification "shouldLeaveValueOnStackAfterPeep()" passes

What is the expected output? What do you see instead?
  I'd expect to get a failure for this specification/test since pop() is
always returning a null and that shouldn't be equal to a String.

What version of the product are you using? On what operating system?
Instinct 0.1.5  on Ubuntu Linux 7.10

Please provide any additional information below.
  I was running the attached code for StackBehavior within an Eclipse 3.4M3
environment on Linux with Java 1.5.0_14 when I noticed this.  Maybe I'm
missing something, but shouldn't the expect.that() in this function return
a failure?

Hey, thanks for that. I'm unable to reproduce on the latest code base. I'll 
push out
a new release that should address your problems.

I get the following error, which I assume is what you were expecting:

java.lang.AssertionError: 
Expected: same(null)
     got: <1>

BTW, how's Instinct work on Eclipse? Is the JUnit integration functioning OK? I 
don't
know anyone who uses Eclipse, and haven't tried it myself, so am unsure of the
integration. Thanks again.
