--------------------------------------------
[~paulk] FYI kindly
> Trait instance init blocks are called only when there are fields defined in
> same Trait
> --------------------------------------------------------------------------------------
>
> Key: GROOVY-8892
> URL: https://issues.apache.org/jira/browse/GROOVY-8892
> Project: Groovy
> Issue Type: Bug
> Components: Compiler, groovy-runtime
> Affects Versions: 2.5.5
> Reporter: Anton Pryamostanov
> Priority: Major
>
> With ref. to GROOVY-8880, it seems Instance Init Blocks in Traits are
> appended/called only when there are fields defined in the same trait.
> Example:
> {code}
> trait TraitOne {
> {
> System.out.println("Does not work")
> }
> }
> trait TraitTwo {
> Integer instanceCounter //immutable, non-shareable
> {
> System.out.println("Works")
> instanceCounter = 1
> }
> }
> class ClassWithTrait implements TraitOne, TraitTwo {
> }
> new ClassWithTrait().instanceCounter
> {code}
> Output:
> {code}
> Works
> {code}
> Expected output (order may differ):
> {code}
> Works
> Does not work
> {code}
