Message End Event

This below code i am getting parser error like this
ex: "org.camunda.bpm.engine.ProcessEngineException: ENGINE-01009 Error while parsing process.

I am invoking process from message End Event to message Intermeditate throw Event.

${execution.getProcessEngineServices().getRuntimeService().createMessageCorrelation(“jenkinsApp”).processInstanceBusinessKey(“maintaincescheduleprocess”).setVariable(“wonumber”, “WO_Number_Prakash”).correlateWithResult()}

What else does the stack trace say?
