After sending a bunch of UDP datagrams, sleep for 30 seconds, then
this gets printed to console:
[java] Exception in thread "pool-1-thread-1" java.lang.NullPointerException
[java] at
org.apache.mina.filter.executor.OrderedThreadPoolExecutor.getSessionBuffer(OrderedThreadPoolExecutor.java:447)

[java] at java.lang.Thread.run(Thread.java:613)
And then no more messages are ever sent despite how I might try.
If I modify OrderedThreadPoolExecutor like so:
clara:executor wilson$ svn diff OrderedThreadPoolExecutor.java
Index: OrderedThreadPoolExecutor.java

try {
- runTasks(getSessionBuffer(session));
+ if (session != null) {

} finally {
idleWorkers.incrementAndGet();
}
Then all is well. Any ideas? Am I abusing Mina, or is it an honest
to goodness Mina bug?
