Lineage and/or IDEA problem

I have this source code fragment

when I try to generate SetterMethodMatcher class, Lineage will generate SetterMethodMatcher as below

while it should ask me to implement ClassFilter or MethodMatcher. And even better, it should also ask me to extend a class which implemented ClassFilter or MethodMatcher.

Same problem if I generate SetterMethodMatcher as an inner class.

I'm using Lineage 3.0.7. But maybe it's the problem of IDEA: http://www.jetbrains.net/jira/browse/IDEA-16828
