constructor delegation in nested class breaks Java backend

[MikhailMalyutin]

Next code:

shared void run(){
    A();
}

class A(){
    shared class B{
        shared Integer i;

        shared new(Integer i){
            this.i = i;
        }

        shared new custom(Integer i, Integer j) extends B(i+j){}

    }
}

produce next error:

Error:ceylon: An unknown error occurred in the Java backend. See previous messages for more information.

To be clear, the problem here is with constructor delegation in nested classes. The workaround is to not use constructor delegation, like this:

class A(){
    shared class B{
        shared Integer i;

        shared new(Integer i){
            this.i = i;
        }

        shared new custom(Integer i, Integer j) {
            this.i = i+j;
        }

    }
}
