What version of the product are you using? On what operating system?
I am using the latest version downloaded using Eclipse  -> Install New Software 
option installed on September 29, 2010

Please provide any additional information below.
It looks like in the AnnotationDatabase file on line 566 the statement  
method.resolveBinding() returns null when the following method is analyzed: 
    /**
     * Get all listeners available on servers created by this factory
     * 
     * @return The current listeners
     */
    public Map<String, Listener> getListeners() {
        return serverContext.getListeners();
    }

Regards,

Radu

A small clarification: I used Crystal versions 3.4.1 and 3.4.2, with Eclipse 
3.5.2 and 3.6.1, the same error occur.

I hope this help,

I am looking forward to hear from you,

Regards,

Radu

Radu,

The AnnotationFinder was recently removed actually, since it was buggy, slow, 
and not really being used. We will be pushing out a more stable version of 
Crystal in the next couple of weeks. If you would like to access the new 
version now, you can get it from the source repository.

Thanks for reporting the issue. I tried to run the latest version of Crystal to 
make sure it fixed your issue, but I could not since I couldn't build your 
example file. Perhaps you could give it a try, using the latest source version 
of Crystal, and make sure it works? Or instead, perhaps you could post a link 
to a jar file that would enable us to build your example? 
Thanks. 
PS - I'm going to call this Fixed rather than WONTFIX.
