Indeed, there is a clash between JCC's suffixing things it generates with 
'Type' and that class name. JCC should use something more rare, such as 
'__Type', for example, or, better yet, allow a parameter to specify the 
suffix. At least, it should be less hardcoded than now.

While the fix is relatively easy to implement, it requires a lot of edits.
I should have something tomorrow.
