Demo jpa-cdi-testing does not work on java 14
As I'm trying to setup our projects to make JPA tests possible without using Arquillian (which is a pain due long deployment times on WAS 9) I found @gunnarmorling demo jpa-cdi-testing project which seems to do exactly this.
So I just cloned it, importet it into IntelliJ and executed the tests. But both fail with this error message:

Would really see this demo working again so I can try to adopt things of it for our scenario.
That's a compatibility issue with Java versions, see https://github.com/jbossas/jboss-classfilewriter/issues/18. This was implemented based on JDK 8 back then, dependencies would need updating for newer JDKs. Perhaps you could send a PR for doing so?
Ah thanks! After switching to JDK 8 the demo project works fine. Will have a look if I can manage to update the dependencies. Could take some time as I'm still struggeling (understanding) with all this WELD stuff. But I'll keep in mind!
