Intellij includes a nice parameter name hint feature (Intellij idea - how to always show method parameter names)
Is it planned for Eclipse incorporate it too?
Angelo Zerr is working on this in his "JDT Codemining" project at https://github.com/angelozerr/jdt-codemining.
It won't be part of the upcoming Eclipse Photon release in June, but may be part of one of the next releases (Eclipse is switching from the yearly release cycle to to having a release every 3 month, so the next release will be in September).
He writes that by starring his project on github you can increase likeliness of this being included soon and you can help by testing and reporting issues.
