-----------------------------------
Assignee: Eric Milles
> Trait method calling closure cannot be inherited while using CompileStatic
> --------------------------------------------------------------------------
>
> Key: GROOVY-7843
> URL: https://issues.apache.org/jira/browse/GROOVY-7843
> Project: Groovy
> Issue Type: Bug
> Reporter: Arnaud CAVAILHEZ
> Assignee: Eric Milles
> Priority: Minor
>
> A trait extending another and calling itself more than 3 times:
> {code}@CompileStatic
> trait UpperTrait {
> void call(Closure body){
> body()
> }
> }{code}
> {code}@CompileStatic
> trait LowerTrait extends UpperTrait {
> void threeCalls() {
> call {
> call {
> call {
> }
> }
> }
> }
> }{code}
> Will generate a `ClassCastException` when called:
> {code}class ImplementsTrait implements LowerTrait {
> }
> new ImplementsTrait().threeCalls()
> {code}
> raises:
> {code}Caught: java.lang.ClassCastException:
> LowerTrait$Trait$Helper$_threeCalls_closure1 cannot be cast to UpperTrait
> java.lang.ClassCastException: LowerTrait$Trait$Helper$_threeCalls_closure1
> cannot be cast to UpperTrait
> at
> LowerTrait$Trait$Helper$_threeCalls_closure1$_closure2.doCall(LowerTrait.groovy:9)
> etc..{code}
