Eric Milles updated GROOVY-10617:
---------------------------------
Component/s: Compiler
> Return statement insertion generates unnecessary dynamic cast
> -------------------------------------------------------------
>
> Key: GROOVY-10617
> URL: https://issues.apache.org/jira/browse/GROOVY-10617
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Minor
> Labels: invokedynamic, performance
> Fix For: 5.0.0-alpha-1
>
>
> Consider the following:
> {code:groovy}
> String m() {
> // return null
> }
> {code}
> The null return is implicit (inserted by {{ReturnAdder}}) but also generates
> an invokedynamic cast instruction when the return type is anything besides
> Object.
