Subject [jira] [Commented] (GROOVY-8338) Calling Stream.of from groovy class in JDK 9 fails
Date Sat, 13 Jan 2018 13:03:00 GMT

    [ https://issues.apache.org/jira/browse/GROOVY-8338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16325122#comment-16325122
] 

Jochen Theodorou commented on GROOVY-8338:
------------------------------------------

What I fixed is the  proxy generator callsite caching is using to make the call. So as long
as the call is done through the proxy it should work. Or so I thought. the message tells me
that the proxy class is loaded but incorrect. It tells me that me fix is not applied for it
actually and that this still generates the old proxy version we still require because those
people cannot keep java9 and java8 working properly together at times. I think it depends
on the VM if it works or not.

> 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.
