Created workflow with start node->script Task-end node.
In script node i have added below code.
In java 8,

var log = org.apache.commons.logging.LogFactory.getLog("a.b.javascript.JavaScriptLogger");
log.debug(" ============================= Staring Execution: ================== ");

This is working properly in script node. Logs are printing in the log file

In java 11, same code is not working. It is throwing below exception

It is not loading the class org.apache.commons.logging.LogFactory. But class is available in the classpath.

Could someone help to resolve this issue.

Appreciate your help on this.
