Disable STS (Eclipse) "Stub Method" suggestion

The question is about Eclipse configuration (I'm actually using STS, but it's pretty much the same). Every time I declare some field in the Eclipse class, I offer me Method stub

as the first position and only then the required class, eg. if I want to create an EntityManager field it first suggests Enti():void - method stub

and only then the EntityManager I need: I never use this stub method (leaving alone that it doesn't make sense to suggest method names starting with a capital letter), so I really would like disable it, but I've played around a lot with different types of settings and still can't find it.
Does anyone know if this is possible at all?
Thanks in advance.
