Look at section 4.1 of the Jess 6.1 manual, where it talks about
JessExceptions:
Another important tip: the JessException class has a method
getNextException which returns non-null when a particular
JessException is a wrapper for another kind of exception. For
example, if you use the Jess function call to call a function
that throws an exception, then call will throw a JessException,
and calling JessException.getNextException() will return the real
exception that was thrown. Your JessException handlers should
always check getNextException(); if your handler simply displays
a thrown exception, then it should display the return value of
getNextException(), too.
That's what's happening here: the stream is throwing an
IOException, and Jess is just passing it along. Fix your catch block
to report the nested exception and you'll find out what's going wrong.
