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

{code}
it's not caused by vertex itself as it works on jdk9.

> Calling Stream.of from groovy class in JDK 9 fails

> 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.
