Util Packages Are Evil
framework names sounds great but are too generic as package names. Such names are un-cohesive by nature. Because of the abstract naming, they end up being a "kitchen sink". All inconvenient classes are placed in the "util" packages what makes such packages bloated, the classes harder to find and the application harder to maintain.
Instead of naming a package util, name it after it true responsibilities e.g. logging, monitoring etc. It will keep the packages small and the application easier to maintain.
