[jira] [Updated] (GROOVY-7843) Trait method calling closure cannot
be inherited while using CompileStatic
[ https://issues.apache.org/jira/browse/GROOVY-7843?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arnaud CAVAILHEZ updated GROOVY-7843:
-------------------------------------
Description:
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}
was:
