Error Initializing Activiti Process Engine using version 5.19.0.2

I am trying to start a very basic messaging event for a proof of concept.

public static void main(String[] args) throws InterruptedException {
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        RuntimeService runtimeService = processEngine.getRuntimeService();
        for(int i=0;i<10;i++) {
            ProcessInstance message = runtimeService.startProcessInstanceByMessage("gaap");
            Thread.sleep(60000);
        }
}‍‍‍‍‍‍‍‍‍

When i try to run i get the following exception:

Exception in thread "main" org.activiti.engine.ActivitiException: couldn't initialize process engine from spring configuration resource file:/{filepath}/activiti-context.xml: Class org.activiti.engine.ProcessEngines can not access a member of class org.activiti.spring.SpringConfigurationHelper with modifiers "public static"

It quess it is happening because the class org.activiti.spring.SpringConfigurationHelper is not public
I can't seem to find a workaround.
Can someone tell me how to start a runtime service without hitting this class, fix the problem or how to start a message event without a runtime service.

My gradatuted in advance

So is your process engine config xml via Spring? Or how do you want to boot up your process engine.

Anyway, a more direct approach would be not to use the getDefaultProcesEngine() method, but instantiate a new one yourself, for example new StandaloneProcessEngineConfiguration().
