-----------------------------------

Thanks! Your results with and without @CompileStatic would also potentially be useful information.

> 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.
