While Googling, I came across on of your blogs
(http://nanthrax.blogspot.com/2021/04/whats-new-in-apache-karaf-431.html) that
one of the changes in Karaf was to export the java.* packages. Could that be
the cause?

|Hi
|
|No sure, it’s only class loader issue. I remember this issue in pure spring
boot
|with JDK11.
|
|Let me check.
