> Hi, guys:
> I got NPE when I wrote the following codes:
> {code:java|title=Groovy Script|borderStyle=solid}
> trait T {
>     def x = 'abc'
> }
> import groovy.transform.TupleConstructor
> @TupleConstructor(includeFields = true)
> class A implements T {
>     def a
>     private b
> }
> assert 'ABC' == new A().x.toUpperCase()
> {code}
> I found that it will works well if I remove {{(includefields = true)}}.
