I've 2 questions...
I can't use the kotlin-plugin, because I get errors all the time and it only recognizes the java-methods.

my questions:
1. Does Kotlin filter out duplicated errors, cause the "Report to JetBrains is disabled".

2. Can I downgrade kotlin-plugin, without loosing the patches, as reported on https://stackoverflow.com/questions/35649488/how-to-downgrade-kotlin-in-intellij-15 So I can use the plugin again?
