the steps:
1. Draw a bpmn diagram with human task, save it, and close it.
2. Reopen it and when try to double click the human task or click User Task tab or I/O Parameters tab in Properties view, the error will be thrown.
Except kepler, other versions such as Mars, Luna, Neon have the same problem.
