Oh~~,
{code:java}
?[...]{code}
is a new feature.

 

For your suggestion, +1, it's easier to distinguish Safe Indexing and Ternary Operator.

> Hi,  I got NPE instead of empty string when I wrote the following snippet:
>  
> {code:java}
> static String a() {
>  null
> }
> static String b() {
>  ''
> }
> def x = a() ? [b(), a()].join(',') : b() // NPE
> //def x = a() ? [b(), a()] : b() // OK
> //def x = a() ? ([b(), a()]).join(',') : b() // OK
> x == ''
> {code}
