I am trying to create an ORM using sleep mode I am using the oracle 11g database and I get this error after creating a sleep generation configuration

java.lang.reflect.InaccessibleObjectException: Unable to make field java.util.ArrayList jdk.internal.loader.URLClassPath.loaders accessible: module java.base does not "opens jdk.internal.loader" to unnamed module @6a75c1c8
Unable to make field java.util.ArrayList jdk.internal.loader.URLClassPath.loaders accessible: module java.base does not "opens jdk.internal.loader" to unnamed module @6a75c1c8

The exception seems justified if there is a type in your class path that is trying to access jdk.internal.loader.URLClassPaththat is used as an inner class in the JDK and exported specifically to java.desktop, java.instrumentand java.loggingmore.

A little more about an unnamed module : -

( ) - VM args::

--add-opens java.base/jdk.internal.loader=ALL-UNNAMED

, jdk.internal.loader java.base .
