Hi Alex,
I am trying to use this library to autmate Swing GUI testing.
My application has a menu and I am trying to click in File -> Open menu using 
the following:
JMenuItemFixture menu = window.menuItemWithPath("File", "Open");
menu.click();

However I am seeing this error message:

java.lang.NoSuchMethodError: 
org.fest.assertions.ObjectAssert.as(Ljava/lang/String;)Lorg/fest/assertions/Obje
ctAssert;
    at org.fest.swing.fixture.JMenuItemFinder.menuItemWithPath(JMenuItemFinder.java:49)
    at org.fest.swing.fixture.ContainerFixture.menuItemWithPath(ContainerFixture.java:267)
    at 

Any help is appreciated.
I am using the latest version of the library Fest-Swing 1.2.2
