In Eclipse I was able to register a set of classes for static import auto-completion, e.g. Math., Assert., EasyMock.*
With this enabled I was able to hit ct
Settings -> Code Style -> Java -> Imports (tab).
Settings -> Code Style -> Imports
In the middle of the pane is the "Packages to Use Import with '*'" table. You can add an entry here of a fully-qualified class name, and tick the static box; now all static methods in this class will be available for auto-completion.
(I'm not sure how the static import works with specifying a package, as I've never tried it, but I don't see why it wouldn't. Specifying a super-package and ticking the "with subpackages" option could be even more interesting.)
