singleton error trace

const class Main{
  static Void main(){
      s:=MyObj.cur
  }
}

const class MyObj{
  static const MyObj cur:=MyObj()

  private new make(){
    throw MyErr("this is my error")
  }
}

const class MyErr:Err{
  new make(Str m):super(m){}
}

a not clearly error trace:

sys::Err: java.lang.ExceptionInInitializerError
  Temp_0::Main.main (/D:/Temp/fan/Temp.fan:3)
  java.lang.reflect.Method.invoke (Unknown)
  fan.sys.Method.invoke (Method.java:536)

That is just the JVM does things - it is not super great at reporting exceptions in initializers. Although the fact that these days you get something is way better than it used to be in the old days.

Thanks for your troubles.I appreciate your help very much.
