Automatic cleanups in tests and in ui (eclipse-jdt#582)
* Use primitive boolean instead of the boxed value * Use String.replace instead of String.replaceAll when regexp is not needed * Use static inner classes * Use StringBuilder instead of StringBuffer * Use method references instead of lambdas * Replace String concetanation with StringBuilder * Fixing primitives to String conversion * Use pattern matching for instanceof
