Finally works ... Made some code adjustments to launch a thread from the CustomWorkItemHandler and pass the KnowledgeSession as follows:

import org.drools.runtime.process.*;

public class CustomWorkItemTask implements Runnable {
    private WorkItem item;
    private WorkItemManager manager;

    public CustomWorkItemTask(WorkItem item, WorkItemManager manager) {
        this.item = item;
        this.manager = manager;
    }

    @Override
    public void run() {
        System.out.printf("\n-----> Waiting in custom work item %s <ID:%d> for 60 secs\n", item.getName(), item.getId());

        // Artificial wait
        try {
            Thread.sleep(60000);
        }
        catch (Exception ex) {
        }

        System.out.printf("\n-----> Completing custom work item %s <ID:%d>\n", item.getName(), item.getId());

           manager.completeWorkItem(item.getId(), null);
    }
}

// -------------------------------------------------------------


import org.drools.runtime.*;
import org.drools.runtime.process.*;

public class CustomWorkItemHandler implements WorkItemHandler {
    private KnowledgeRuntime ksession;

    public CustomWorkItemHandler(KnowledgeRuntime session) {
        this.ksession = session;
    }

    @Override
    public void executeWorkItem(WorkItem item, WorkItemManager manager) {
*        // NOTE: Cannot use the WorkItemManager passed into the method - It will throw the following exception:*
*        //       javax.persistence.TransactionRequiredException: No active JTA transaction on joinTransaction call*

        CustomWorkItemTask task = new CustomWorkItemTask(item, ksession.getWorkItemManager());

        new Thread(task).start();
    }

    @Override
    public void abortWorkItem(WorkItem item, WorkItemManager manager) {
    }
}

Hope this is helpful for someone
