Why do I get an UnifnishedStubException in Mockito when the stub looks as per documentation?

I have the following test file using Mockito framework:

    @Rule
    public ExpectedException expectedException = ExpectedException.none();

    @Spy    
    private JarExtracter jExt = Mockito.spy(JarExtracter.class);

    @Test
    public void inputStreamTest() throws IOException {
        String path = "/edk.dll";       

        // Call the method and do the checks                    
        jExt.extract(path);                 

        // Check for error with a null stream
        path = "/../edk.dll";       
        doThrow(IOException.class).when(jExt).extract(path);   
        jExt.extract(path);

        verifyNoMoreInteractions(jExt);        
        expectedException.expect(IOException.class);
        expectedException.expectMessage("Cannot get");

doThrow() line returns:

org.mockito.exceptions.misusing.UnfinishedStubbingException: 
Unfinished stubbing detected here:
-> at confusionIndicator.tests.JarExtracterTests.inputStreamTest(JarExtracterTests.java:30)

E.g. thenReturn() may be missing.
Examples of correct stubbing:
    when(mock.isOk()).thenReturn(true);
    when(mock.isOk()).thenThrow(exception);
    doThrow(exception).when(mock).someVoidMethod();
Hints:
 1. missing thenReturn()
 2. you are trying to stub a final method, you naughty developer!
 3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed

I tried different approaches to testing this error throwing behaviour, but I just cannot get rid of this error message which makes my test fail. Any help will be substantially appreciated!
