I would find extremely useful if JDT provided some code templates for some Java 8 features. Above all, a lambda code template, that allows you to type zero or more parameters (having it be context sensitive would be great!) and automatically adds the necessary structure, i.e.: () -> { }.

Here are some examples (which however seem not to be context sensitive): https://github.com/Tasktop/eclipse-templates

As an example, let Validator be javax.faces.validator.Validator, with its functional method be javax.faces.validator.Validator.validate(FacesContext, UIComponent, Object):

public class MyClass {

  private Validator myValidator = lamb| <= invoke code assist here

}

let "lambda" be the code template name, the completion could be:

public class MyClass {

  private Validator myValidator = (context, component, value) -> {
    | <= cursor here
  }
}
