[kepler-users] Problem with PN director

[Edward A. Lee]

Something's fishy here.
Such a model should work fine in PN.
Note that hasToken() _alaways_ returns true in PN.
The get() method blocks when there is no input.

Looks like something is terminating the threads
using a TerminateProcessException. How is your model
supposed to be stopped?
