The culprit is probably on eu.ngong.ehour.tracking.impl.Run.run(Run.java:114).
The exception trace seems incomplete, I'm not seeing the trace of the
CayenneRuntimeException. If you have code like
try {
...
} catch (Exception e) {
throw TrackingException ("Unexpected exception: " + e);
}
this is the kind of unhelpful trace your're getting. You should probably do
try {
...
} catch (Exception e) {
throw TrackingException ("Unexpected exception", e);
}
Then your TrackingException will be "chained" with the original exception, and
you'll get a trace for your exception, a line of "caused by:", and the full
trace of the CayenneRuntimeException, which would then allow people to take a
look where this originated from inside Cayenne and give hints what could be
wrong.
(This is probably unrelated to the logging problems you're experiencing.)
