Code duplication caused by primitive types: How to avoid insanity?

Question

In one of my Java projects I am plagued by code repetition due to the way Java handles (not) primitives. After having to manually copy the same change to four different loca

Answer 1

Does Java 7 have any changes that might ease the strain in such cases?

No.

Is there somewhere an annotation processor to handle this case?

Not that I am aware of.

If not, what would it take to build one?

Time, or money. :-)

This seems to me like a problem-space where it would be difficult to come up with a general solution that works well ... beyond trivial cases. Conventional source code generation or a (textual) preprocessor seems more promising to me. (I'm not an Annotation processor expert though.)
