Support Compact Constructors in Records

[pcimcioch]

Library could support compact constructors in java records:

record Foo(String name, int x, int y) {
  Foo {
    Objects.requireNonNull(name);
  }
}

Currently, as a workaround you can ovveride the whole default constructor:

record Foo(String name, int x, int y) {
    Foo(String name, int x, int y) {
        this.name = Objects.requireNonNull(name);
        this.x = x;
        this.y = y;
    }
}
