This may not be a good posting for "Beginners Corner", but I sure wasn't able to find another forum that seemed like a good fit. Here goes.
We are using the org.jboss.varia.scheduler.ScheduleManager class, and have been getting ClassCastExceptions. Looking at the code, I can see why. There are a number of places where there is code like this:
Iterator i = mSchedules.entrySet().iterator();
while (i.hasNext()) {
ScheduleInstance lInstance = (ScheduleInstance) i.next();
...
Unless the mSchedules map is empty, this code is going to throw a ClassCastException every time, because the entrySet method on a Map produces a set of Map.Entry objects. The code should say something line the following instead:
Iterator i = mSchedules.values().iterator();
while (i.hasNext()) {
ScheduleInstance lInstance = (ScheduleInstance) i.next();
...
If you need the key and the value, you would do something like:
Iterator i = mSchedules.entrySet().iterator();
while (i.hasNext()) {
Map.Entry entry = (Map.Entry) i.next();
Integer id = (Integer) entry.getKey();
ScheduleInstance lInstance = (ScheduleInstance) entry.getValue();
...
I would be happy to submit a bug report, if someone could (politely) point me to the right place to do so.
