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

I've just built groovy-all jar from latest commit on 2.4.X branch, included it in my test project and the following test
{code}class StaticMethodCall extends Specification {

    def 'static method call test'() {
        expect:
        Stream.of(1, 2, 3).map({ it + 1 }).collect(Collectors.toList()) == [2, 3, 4]
    }

}{code}
passed on jdk 9.0.1

However, there's still something broken. I've added a static Vertx.vertx() call
{code}
class StaticMethodCall extends Specification {
    def 'static method call test'() {
        expect:
        def vertx = Vertx.vertx()
        true
    }
}{code}

and it fails with:
{code}
java.lang.VerifyError: (class: io/vertx/core/Vertx$vertx, method: callStatic signature: (Ljava/lang/Class;[Ljava/lang/Object;)Ljava/lang/Object;) Illegal type in constant pool

        at java.base/java.lang.Class.privateGetDeclaredConstructors(Class.java:3110)
        at java.base/java.lang.Class.getConstructor0(Class.java:3315)
        at java.base/java.lang.Class.getConstructor(Class.java:2108)
        at com.example.app.StaticMethodCall.static method call test(StaticMethodCall.groovy:9)
{code}

it's not caused by vertx itself as it works on jdk9, it only fails in groovy.

>                 Key: GROOVY-8338
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8338
>             Project: Groovy
>          Issue Type: Bug
>          Components: groovy-runtime
>    Affects Versions: 2.4.12
>            Reporter: Marcus Nylander
>
> 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.
