Nikolay Chashnikov created GROOVY-10459:
-------------------------------------------
Summary: Compilation of code which accesses array element of
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
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.
