A small number of people have been seeing an error when using the BPMN process editor in JDeveloper 11.1.1.6 (PS5). The symptom is a NullPointerException, as seen in the log, an example below, and a dialog box telling you an unexpected error has occurred (see image below).
If you hit this issue, you should log a service request with Oracle Support and ask for a patch for bug number 13088538. You will need to provide details about your JDeveloper environment, versions of plugins, etc.
