* Consistenty use javax annotations. - Unfortunately jetbrains annotations seem to be exposed transitively via core somewhere, but with the correct IDE settings, annotations can be defaulted to javax - Cleaning up of import order in #1195 - Must be merged before #1195 * Add and apply .editorconfig from P2 - Does not rearrange entries * Address some comments * add back some javadoc comments * Address final comments Co-authored-by: NotMyFault <mc.cache@web.de>
