initialization behavior with MutablePersonWrapperBuilder

[shawkins]

This class looks like:

public MutablePersonWrapperBuilder(MutablePersonWrapper instance,Boolean validationEnabled) {
    this.fluent = this; 
    if (instance != null) {
    }
    this.validationEnabled = validationEnabled; 
  }
  MutablePersonWrapperFluent<?> fluent;
  Boolean validationEnabled;
  public EditableMutablePersonWrapper build() {
    EditableMutablePersonWrapper buildable = new EditableMutablePersonWrapper();
    buildable.setItem(fluent.buildItem());
    return buildable;
  }

There's no attempt to initialize the builder item when the instance is not null. This behavior is not new, in .94 it looked like:

  public MutablePersonWrapperBuilder(MutablePersonWrapper instance,Boolean validationEnabled) {
    this.fluent = this; 
    this.validationEnabled = validationEnabled; 
  }

Shouldn't there be an attempt to call withItem(instance.getItem())?
