-----------------------------------
Summary: .ClassLoaderUtils.setThreadContextClassloader attempts to
set null class loader
Key: CXF-8603
URL: https://issues.apache.org/jira/browse/CXF-8603
Project: CXF
Issue Type: Bug
Affects Versions: 3.3.11
Reporter: Archie Patrick
Attachments: image-2021-09-30-11-38-45-171.png
Created a custom connector for a SOAP Service using CXF for Oracle Identity
Manager using their Identity Connector Framework (ICF). Their framework has a
Context Class Loader "watcher" that detects that the
ClassLoaderUtils.setThreadContextClassLoader() method is attempting to set a
"null" loader. This happens when a call is made to invoke a SOAP message:
public void testService() {
try {
IPersonnelManagement2014 port = getPersonnelManagementPort2014();
PersonnelManagementViewUser2Response response =
port.viewUser("xxxxx", "external", null, null, null, null);
