sdb does not correctly stop at breakpoints in Java files

[chipsenkbeil]

Attaching a sample Java program run via

java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y com.example.Main

Attaching resumes the JVM immediately (should it?).

Setting breakpoints on the first two lines in main via

bp "com/example/Main.java" 58
bp "com/example/Main.java" 59

does not trigger an actual breakpoint.

package com.example;

import java.util.List;
import java.util.ArrayList;

public class Main {
    private static enum Gender {
        MALE, FEMALE, OTHER
    }

    private static class Person {
        public final String firstName;
        public final String lastName;
        public final int age;
        public final Gender gender;

        public Person(
            final String firstName, 
            final String lastName, 
            final int age, 
            final Gender gender
        ) {
            this.firstName = firstName;
            this.lastName = lastName;
            this.age = age;
            this.gender = gender;
        }

        @Override
        public String toString() {
            final StringBuilder sb = new StringBuilder();

            sb.append("==PERSON==");
            sb.append("\n");

            sb.append("Name: ");
            sb.append(this.firstName);
            sb.append(" ");
            sb.append(this.lastName);

            sb.append("\n");

            sb.append("==========");
            sb.append("\n");

            return sb.toString();
