A DESCRIPTION OF THE PROBLEM :
he JavaScript enginge initialized good… but later during validating/executing specific JS script fails:

MAIN REASON -> limitation access to internal classes in JDK 17:
Related to JDK17 & new standalone JS Engine:
Main reason limitation in JDK17 with access to internal “deprecated” classes:
Caused by: java.lang.NoSuchMethodError: 'java.lang.Class sun.misc.Unsafe.defineAnonymousClass(java.lang.Class, byte[], java.lang.Object[])'

REGRESSION : Last worked in version 16.0.2

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Any small application with Java + Nashorn...

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should be executed JavaScript code without issues
ACTUAL -
Related to JDK17 & new standalone JS Engine (Nashorn standalone 15.3):
Main reason limitation in JDK17 with access to internal “deprecated” classes:
Caused by: java.lang.NoSuchMethodError: 'java.lang.Class sun.misc.Unsafe.defineAnonymousClass(java.lang.Class, byte[], java.lang.Object[])'

CUSTOMER SUBMITTED WORKAROUND :
Not exist on Java 17.

FREQUENCY : always
