Daniel Sun commented on GROOVY-8338:
------------------------------------

The following code still fails when running on Java9
{code}
$ java -Xmx32m -version
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)
$ javac -J-Xmx32m -version
javac 9.0.1
{code}

{code:java}
assert [2, 3, 4] == Stream.of(1, 2, 3).map(e -> e + 1).collect(Collectors.toList());
{code}

> Trying to call Stream.of from groovy class (groovy version 2.4.12) using JDK 9 (jdk 9 181) fails. 
> Example:
> {code}
> package test
> import java.util.stream.Stream
> class B {
>     static void main(String[] args) {
>         Stream.of("1").forEach({ println(it) })
>     }
> }
> {code}
> The code above fails with:
> Exception in thread "main" java.lang.IncompatibleClassChangeError: Method java.util.stream.Stream.of(Ljava/lang/Object;)Ljava/util/stream/Stream; must be InterfaceMethodref constant
> 	at java_util_stream_Stream$of.call(Unknown Source)
> 	at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48)
> 	at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:113)
> 	at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:125)
> 	at test.B.main(B.groovy:7)
> The same occurs for other interface static methods also:
> {code}
> public interface D {
>     static D of(String s) {
>         return new D() {
>         };
>     }
> }
> class C {
>     static void main(String[] args) {
>         D.of("1")
>     }
> }
> {code}
> Also fails with:
> Exception in thread "main" java.lang.IncompatibleClassChangeError: Method test.D.of(Ljava/lang/String;)Ltest/D; must be InterfaceMethodref constant
> 	at test.D$of.call(Unknown Source)
> 	at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48)
> 	at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:113)
> 	at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:125)
> 	at test.C.main(C.groovy:7)
> Running with JDK 8 works fine.
