The problem was the following. I had something like this code:
public class Class extends AbstractClass {
public void increaseSomething(){
super.something++;
}
public void addSomethingElse(int value){
super.somethingElse += value;
}
}
After I deleted both super's the compiler runs successfully thru. I know that this was my failure but it would be nice if the compiler can print out such failure or the IDE could.
