If you want run on own set of data or modify checks and calculations, then
get 2.5.0p6 from
http://datacenter.gradsoft.ua/public.repository/ua.gradsoft/javachecker/installations/JavaCheckerSourceInstaller-2.5.0p6.jar
 than as described in my first letter.

// NewInteger is sum of bytes + widening (?) + big literals.
// Elvis - sub of elvis and null-safe.
// CollectionLiterals: when we see 2 or bigger put(x,y) where x and y are
constants, or 2 or bigger add(constant) or Arrays.asList(constants...)
