Romain Manni-Bucau commented on OWB-1260:
-----------------------------------------
Proxying needs to be able to define the proxy class in the classloader. For
this we use defineClass method of the contextual or class classloader. If not
available like on java 11 we use unsafe bit unsafe is not available if not
open. This config solves it.
