Description
Upgrading a client application from Java 15 to Java 16 connecting to remote EJB on a WildFly server fails with this error:

This seems related to JEP-396
- Code that uses reflection to access private fields of exported java.* APIs will no longer work by default. For example,
{{var ks = java.security.KeyStore.getInstance("jceks");
var f = ks.getClass().getDeclaredField("keyStoreSpi");
f.setAccessible(true);}}
will fail with an exception of the form
{{Exception in thread "main" java.lang.reflect.InaccessibleObjectException:
Unable to make field private java.security.KeyStoreSpi
java.security.KeyStore.keyStoreSpi accessible: module java.base does
not "opens java.security" to unnamed module @6e2c634b}}
I realize that WildFly does not support Java 16 yet
