[wildfly-dev] common cdi-tck problem on wildfly with java 9

[Scott Stark]

I don't see that those issues deal with the change in behavior regarding a null parent class loader. They deal with the inability to add reads that are apparent cycles and the addition of a ClassLoader.get PlatformClassLoader() method, which has been added in build 126. I have submitted a bug with the test example found here: https://github.com/RedHatJava9Testing/URLClassLoader.git

Ok, I'll look at those, but I am using the b126 build. Maybe the fix slipped.

[tmp 512]$ java -version
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+126)
Java HotSpot(TM) 64-Bit Server VM (build 9-ea+126, mixed mode)

This is one of known issues, see for details:
http://openjdk.java.net/projects/jigsaw/spec/issues/#module-graphs
http://openjdk.java.net/projects/jigsaw/spec/issues/#ClassFilesAsResources
http://openjdk.java.net/projects/jigsaw/spec/issues/#PlatformClassLoader

Some of this is being addressed as part upcoming jigsaw b126
