The module framework boot delegation permits com.sun.el.* which is incompatible with JSF portlets on WebLogic

Problem Background

LPS-65488 fixed a problem that manifested itself on WildFly. The solution was to make the com.sun.* wildcard to be less inclusive by changing it to com.sun.ccpp.*, com.sun.crypto.*, com.sun.el, com.sun.el.*.

However, on WebLogic com.sun.el, com.sun.el.* must not be included in the value.

Steps to Reproduce:

1. Start WebLogic 12c R2

2. Deploy the jsf-applicant-portlet (see attachment)

Expected Results

No errors appear in the log and the portlet can be added to a portal page.

Actual Results

The following appears in the WebLogic server log:
