Eric Milles commented on GROOVY-8788: ------------------------------------- 6. mixed declaration and extension (pt.2) {code:groovy} class A { int m(String s) {4} } class B extends A { } class C extends B { } class Ext { static m(B self, Object o) {2} } use (Ext) { def a = new A() assert a.m(new String()) == 4 def b = new B() assert b.m(new Object()) == 2 assert b.m(new String()) == 4 def c = new C() assert c.m(new Object()) == 2 assert c.m(new String()) == 4 } {code} This case behaves under dynamic and static compilation. So no change required. :) > Inconsistency in extension method selection with @CompileStatic > --------------------------------------------------------------- > > Key: GROOVY-8788 > URL: https://issues.apache.org/jira/browse/GROOVY-8788 > Project: Groovy > Issue Type: Bug > Components: Static compilation, Static Type Checker > Affects Versions: 2.4.15, 2.5.2 > Reporter: Daniil Ovchinnikov > Assignee: Eric Milles > Priority: Major > Labels: breaking > > Given properly registered extension class: > {code:java|title=MyExtensions.java} > public class MyExtensions { > public static void foo(Object self, String s) { > System.out.println("Object#foo(String)"); > } > public static void foo(String self, Object o) { > System.out.println("String#foo(Object)"); > } > } > {code} > Run > {code:java|title=playground.groovy} > void usageExt() { > "".foo("") // prints "Object#foo(String)" which is correct > } > @groovy.transform.CompileStatic > void usageExtStatic() { > "".foo("") // prints "String#foo(Object)" which is questionable > } > usageExt() > usageExtStatic() > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
