Analyzer Feedback from IntelliJ, `unsupported initializer super.{`

[holly-hacker]

I believe I was typing the following, with my cursor at the pipe character. Some references in the file were not yet resolved because I just copy/pasted some code to edit.

ListedGameInfo.fromMap(Map<Object, Object> map) : super.|{

Seems like a very minor issue, everything still works. I don't know if this is an error on WebStorm's side but it suggested opening an issue.
