[jira] [Commented] (GROOVY-8764) Closure inside an anonymous class uses wrong outside class instance with @CS

["Paul King (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-8764?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16641645#comment-16641645 ] 

Paul King commented on GROOVY-8764:
-----------------------------------

This doesn't occur if only the method has @CompileStatic like in this script:
{code}
import groovy.transform.*

@Field String foo = 'FOO'

@CompileStatic
void test() {
    new Runnable() {
        void run() {
            def c = {
                println foo
            }
            c()
        }
    } .run()
}

test()
{code}
Or in this class:
{code}
import groovy.transform.*

class GroovyTest {
    private String foo = 'FOO'
    @CompileStatic
    void test() {
        new Runnable() {
            void run() {
                def c = {
                    println foo
                }
                c()
            }
        }.run()
    }
}

new GroovyTest().test()
{code}
