Many automatic code transformations such as class duplication in a different package, various refactorings as well as automatic import generation causes the white-space characters surrounding the affected code (and, in the case of automatic import generation, non-affected source code) to be replaced with single space characters. For programmers that use vertical / columnar alignments in their code, this eradication of white-space context is disruptive and necessitates much manual recreation of the preferred code formatting.
