Proxying default methods does not work with 5.5.0-beta-2

[Oliver Kaiser]

Hi everyone,

given something like this:

public interface Blub {
   public default String foo() {
     return "Default";
   }
}
public class BlubImpl implements Blub {
   @Override
   public String foo() {
     return "Impl";
   }
}

when calling "registry.getService(Blub.class).foo()" using beta-1 this
works as expected (BlubImpl is called); when using beta-2 only the
default method is called.

the log output of PlasticProxyFactory shows that the method is skipped
in the generated class

seems to be related to this commit
https://github.com/apache/tapestry-5/commit/709d282bfc626ce55cde07cbf909c0b86c2b4bcb#diff-89a017b694cffee07e15608bc316d0d7

now "proxyInterface(Class, PlasticMethod)" only
calls "introduceInterface(Class, PasticMethod)" (which skips the method
as "isDefaultMethod(m)" returns true); earlier versions had an
additional for-loop which handled this case (at least from stepping
though in a debugger it looks that way)


that's a regression, right?


btw: thanks to everyone who worked on the 5.4->5.5 transition; updating
was very smooth!


Regards,
Oliver

Yes, it is. Thanks for spotting it!

I've just committed a fix for this issue.

Hi

I've just gotten around to test our products against Tapestry 5.5
(master/HEAD) - Everything seems to work fine with the latest code, good
work!

Would it be possible to get a tagged beta (or rc) version published to some
repository that we can rely on for stable builds?

I can see several 5.4 beta/rc versions in central (
https://mvnrepository.com/artifact/org.apache.tapestry/tapestry-core ),
that would work well for us. I can see a single 5.4-beta on apache staging,
but it seems unclear how long we can expect things to be present in
"staging".
