Hey Galder, Sanne!
The author is no longer anonymous! It was me [1]!
Jokes aside; Galder - may I ask you to double check your configuration? I extracted formatter archive and it seems to be fine [2]. Perhaps you didn't enable it (watch out, the formatter name was changed some time ago from Horizon to Infinispan) or this is some tooling problem (which probably should be reported to Jetbrains). Anyway - could you please double check it? I'll try to catch you tomorrow on IRC and talk about it...
BTW - There are 2 different errors in your output - the first one is the start import which should be avoided. The second one is duplicated import (also should be avoided). Please don't confuse those two.
@Sanne - before you trow a 'git revert' axe on me - may I ask you to import the latest formatter and check if the amount of imports before replacing them with star looks correctly? It looks fine to me but I may have some old installation, old configuration etc...
Thanks

[2] unzip IntelliJ_IDEA_Code_Style.jar and look into attached XML. Those two properties are responsible for star imports.
