How to access lib-connectors/ Class Path from Plugin ClassLoader

Hello Experts,

We are testing one of our existing plugin with new IIQ versions. (especially 8.2 and 8.3) Per my understanding after 8.2, the connector-bundle.jar has been separated from the ~/WEB-INF/lib to lib-connectors/ folder. And it’s not included in the class path by default.

The Connector (e.g. SAPInternalConnector) we required is located under connector-bundle-misc.jar, the compiliation process went through successfully, however, after plugin deployed, we are getting exception:
2022-12-06T12:10:23,944 ERROR QuartzScheduler_Worker-2 sailpoint.api.TaskManager:934 - Exception: [sailpoint/connector/SAPInternalConnector]
java.lang.NoClassDefFoundError: sailpoint/connector/SAPInternalConnector

We also tried to add the corresponding java class into file: ~/WEB-INF/lib-connectors/connectorVsConnectorBundleMapping.json:
“” : “connector-bundle-misc.jar”. But this is also not working. Normally this will work if the class sits in the standard ~/WEB-INF/lib or ~/classes; but I suspect this is working with Plugin classes, as Plugin is using a different ClassLoader.

So the question will be how can we access class under /lib-connectors from Plugin implementation?

Thanks and Regards,
Mike
