Intellij IDEA autocomplete java core library

Question

I seem to have added the core library to some kind of Autocomplete-Blacklist. If I do new File, it offers only com.sun.java.util.jar.pack.Package.File as autocomplete. This is the same for different Projects, so it seems to be a global option.

I already tried to recreate the SDK under Platform-Setting, without success.

I would appreciate any idea how to fix that.
