[jira] [Commented] (GROOVY-7784) TypeChecked/CompileStatic:
IndexOutOfBoundsException
[ https://issues.apache.org/jira/browse/GROOVY-7784?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15193450#comment-15193450 ]
Shil Sinha commented on GROOVY-7784:
------------------------------------
This occurs during SAM type inference when the target method has a var args parameter for which no argument is supplied - in this case {{Paths.write(Path, Iterable<? extends CharSequence>, OpenOptions...)}}. The number of parameters being greater than the number of arguments causes the exception.

> Key: GROOVY-7784
> URL: https://issues.apache.org/jira/browse/GROOVY-7784
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.4.6
> Reporter: Gregory Moltchadski
>
> Compiling the following:
> {code:title=IOOBE.groovy|borderStyle=solid}
> import groovy.transform.TypeChecked
> import java.nio.file.Files
> import java.nio.file.Paths
> @TypeChecked
> class IOOBE
> {
> def ioobe()
> {
> Files.write(Paths.get('foo.bar'), { ['foo', 'bar'].iterator() });
> }
> }
> {code}
> (closure is used to automatically coerce Iterator to Iterable),
> produces the following exception during compilation:
> {code}
