Facing Error while deploying OCI function while importing libraries

Dears,

I am facing issue while deploying Java OCI function. I am tiring to import the below package , but it keep failed while deploy the function as it not able to find this symbols.

I tried also to import the dependences of this package under func.yaml file but still same issue.

The package :

import sun.security.x509.X500Name;

import sun.security.util.DerOutputStream;

import sun.security.pkcs.PKCS7;

Error Message:

79.94 [ERROR] (package sun.security.util is declared in module java.base, which does not export it to the unnamed module)

79.95 [ERROR] /function/src/main/java/com/example/fn/HelloFunction.java:[45,20] package sun.security.util is not visible
