[jira] [Closed] (GROOVY-10459) Compilation of code which access array element inside CompileDynamic constructor fails
[ https://issues.apache.org/jira/browse/GROOVY-10459?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul King closed GROOVY-10459.
------------------------------
> Compilation of code which access array element inside CompileDynamic constructor fails
> --------------------------------------------------------------------------------------
>
> Key: GROOVY-10459
> URL: https://issues.apache.org/jira/browse/GROOVY-10459
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 3.0.9
> Reporter: Nikolay Chashnikov
> Priority: Major
>
> The following code runs without problem in Groovy 2.5.14:
> {code:groovy}
> import groovy.transform.CompileDynamic
> import groovy.transform.CompileStatic
> @CompileStatic
> class DynamicArrayAccess {
> @CompileDynamic
> DynamicArrayAccess() {
> Node node = loadXml()
> println node.b[0].text()
> }
> private static Node loadXml() {
> new StringReader("<a><b>hello</b></a>").withCloseable { new XmlParser().parse(it) }
> }
> static void main(String[] args) {
> new DynamicArrayAccess()
> }
> }
> {code}
> However, if you try to run it in Groovy 3.0.9, you'll get an exception during compilation. Extracting problematic code to a separate method fixes the problem.
> {noformat}
> BUG! exception in phase 'class generation' in source unit '/home/nik/IdeaProjects/untitled19/src/main/groovy/DynamicArrayAccess.groovy' At line 9 column 21
> On receiver: node.b with message: getAt and arguments: 0
> This method should not have been called. Please try to create a simple example reproducing
