Eric Milles reassigned GROOVY-8643:
-----------------------------------

    Assignee: Eric Milles

> Make for-in null safe for CompileStatic
> ---------------------------------------
>
>                 Key: GROOVY-8643
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8643
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 3.x, 2.4.x
>            Reporter: Sergiy
>            Assignee: Eric Milles
>            Priority: Minor
>
> See following simple script:
> {code:java}
> import groovy.transform.CompileStatic;
> @CompileStatic
> void printList(List l){
>     println "List:"
>     for (Object o in l) {println o}
>     println "Done"
> }
> printList(null)
> {code}
> It crashes with null pointer exception due to list being null in the for 
> loop. However it works perfectly fine when CompileStatic annotation is 
> removed. I believe this inconsistency is a bug as the whole point of 
> introducing a new for-in construct in groovy appeared to be to make it a null 
> safe construct (unlike _for (Object o: l)_ construct in java). However, when 
> compiling statically, it seems to be compiled as the java iterator it 
> replaces, breaking away from groovy convention without even a warning.
> Any chance to have it fixed in 3.x?
