Not able to pull the deadline for a task or process below is the code used.

1. If you are executing this outside a smart service as a standalone Java snippet then you need this line at the beginning of your main method: ConfigurationLoader.initializeConfigurations();

Here is an example that worked for me. I am using two different approaches, the both print the same (getProcessDetails().getPriority() and getPriorityOfProcess() )

ConfigurationLoader.initializeConfigurations();
ServiceContext sc = ServiceContextFactory.getAdministratorServiceContext();
ProcessExecutionService pes = ServiceLocator.getProcessExecutionService(sc);

System.out.println(pes.getProcessDetails(processId).getPriority());
System.out.println(pes.getPriorityOfProcess(processId));

2.If you are using this within a plug-in then it should work but I suggest you use the ProcessExecutionService injected context
