[jira] [Updated] (GROOVY-9861) parsing bug when inner class
references top level class fields in groovy 3
[ https://issues.apache.org/jira/browse/GROOVY-9861?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Howard updated GROOVY-9861:
---------------------------
Description:
The follow code compiles fine under groovy 2 but does not compile under groovy 3
{code}
import groovy.transform.CompileStatic
import java.awt.Color
import java.awt.event.MouseAdapter
import java.awt.event.MouseEvent
@CompileStatic
public class TreePair2 {
int clickCount = 0;
boolean isAprilFools = false;
private TreePair2() {
}
protected class TreeMouseClickHandler extends MouseAdapter {
@Override
public void mouseClicked(MouseEvent e) {
if(isAprilFools) {
clickCount++;
}
}
}
}
""
{code}
Error msg:
{code}
Exception thrown
groovy.lang.GroovyRuntimeException: ASM reporting processing error for TreePair2$TreeMouseClickHandler#mouseClicked with signature void mouseClicked(java.awt.event.MouseEvent) in ConsoleScript77:18. ConsoleScript77
at jdk.internal.reflect.GeneratedMethodAccessor56.invoke(Unknown Source)

at groovyjarjarasm.asm.MethodWriter.visitMaxs(MethodWriter.java:1546)
... 2 more{code}
The problem seems to be with these 3 lines
{code}
if(isAprilFools) {
clickCount++;
}
{code}
if you just have
{code}
if(isAprilFools) {
println(1)
}
// it works
// or just
clickCount++;
// also works
// but when you add clickCount++ into the if statement, it fails
{code}
