[jersey-dev] Jersey 2.40 + JDK 17

[Abhijit Bhatode <abhijit.bhatode@xxxxxxxxx>]

Hello team,

I came across [yasson-dev] Issue with yasson jar in jaxrs-ri-2.27. (eclipse.org). But, we are using Jersey 2.40 with JDK 17.

Yasson version used is 1.03.

Below exception is seen when REST service is sending a response :

---------------------------

Caused By: java.lang.IllegalAccessException: class org.eclipse.yasson.internal.model.GetFromGetter cannot access class sun.reflect.annotation.AnnotatedTypeFactory$AnnotatedTypeBaseImpl (in module java.base) because module java.base does not export sun.reflect.annotation to unnamed module @6c0d7c83
at java.base/jdk.internal.reflect.Reflection.newIllegalAccessException(Reflection.java:392)
at java.base/java.lang.reflect.AccessibleObject.checkAccess(AccessibleObject.java:674)
at java.base/java.lang.reflect.Method.invoke(Method.java:560)
at org.eclipse.yasson.internal.model.GetFromGetter.internalGetValue(GetFromGetter.java:28)

-----------------------------

I tried adding below in module-info.java file and adding the compiled class in the root of the JAR containing the JAXB related model classes. But, this did not work. 

module mycompanyrest {
        opens mycompany.rest.model.policy;
        exports mycompany.rest.model.policy;
}

After adding JVM options --add-opens java.base/sun.reflect.annotation=ALL-UNNAMED &  --add-exports java.base/sun.reflect.annotation=ALL-UNNAMED

error message changed to 

------------------------
Caused By: java.lang.IllegalAccessException: class org.eclipse.yasson.internal.model.GetFromGetter cannot access a member of class sun.reflect.annotation.AnnotatedTypeFactory$AnnotatedTypeBaseImpl (in module java.base) with modifiers "public"

------------------

Thank you for your help in advance.
