Matej Novotny commented on WFLY-11406:
--------------------------------------
On Weld side, we would like to design an SPI that will leverage David's API coming
from jboss-modules (albeit we might need an adjustment there), I started playing around
with that.
However, this needs to addressed in jboss-classfilewriter firstly as everything using it
will simply blow up from the static initializer there.
Should we use simple {{setAccessible()}}, it will work but we'll be getting all those
lovely Illegal access warnings again (which was why we used unsafe).
Sadly, I don't really know how to bypass the new Unsafe limitations (aka how to do
what they did with byte-buddy).
bq. Perhaps MethodHandles.Lookup.defineClass could work for this too but it may not and in
any case is only available from JDK 9 on.
That is the supposed replacement, yet last time I checked it didn't allow to define
classes with (different) {{ProtectionDomain}} which was a showstopper, at least for Weld.
Back there I created a JDK issue but got no answer.
Reflection exception at org.jboss.classfilewriter.ClassFile on JDK12

Key: WFLY-11406
URL: https://issues.jboss.org/browse/WFLY-11406
Project: WildFly
Issue Type: Bug
Components: CDI / Weld, EJB

Fix For: 16.0.0.Beta1
When running WildFly on JDK12 I'm observing this exception due to Unsafe changes in
recent JDK Early Access builds:
