I've sent it to your mail, as I shouldn't upload it on public.

I have checked the test. It looks like some cleaning up is not doing properly. 
I need some time to debug.

I have located the issue. It is because you mock a String in 
EncodeUrlTitleTests.shouldSetUrlTitleToEncodedVersionOfTitle(), which is an 
empty string. And the empty mocked string is later used by Grails.

I think a potential fix of this bug is giving the String type special treatment 
while creating an instance of String inside Gmock.

OK, I finally figure it out. It is a bug of MetaClassRegistryCleaner in Grails. 
I cannot fix it on the side of Gmock. A patch to Grails is needed.

Thanks for spending your time on this. I hope Grails team will get it fixed, as 
gmock is by far the best mocking framework for Groovy.

I am trying fix the bug, as I have already spent much time on it. :)

A patch is submitted, but you may have to wait for Grails 2.0.1.
