Description

Hi, guys:

I got NPE when I wrote the following codes:

Groovy Script

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()

I found that it will works well if I remove (includefields = true).
