mina 2.0.2 - NullPointerException in AbstractPollingIoProcessor
Dear forum, I'm using mina 2.0.2 and once in a while I get this error in the console: Exception in thread pool-4-thread-1 java.lang.NullPointerException at org.apache.mina.core.polling.AbstractPollingIoProcessor$Processor.run(Ab stractPollingIoProcessor.java:1151) at org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.j ava:64) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) In my server I have use a NioSocketAcceptor and at some point, although it might not be relevant, I unbind() the acceptor, replace IoFilter with a new one and then bind() it again. BTW, I didn't find line 1151 in AbstractPollingIoProcessor... Any idea why this might happen? Thanks in advance, Guy

RE: mina 2.0.2 - NullPointerException in AbstractPollingIoProcessor
No. I wonder if you experienced such an error before... Emmanuel, I can debug it myself but the problem is that AbstractPollingIoProcessor is shorter than 1151 lines while in the exception trace we can see that line 1151 is the cause of the exception. Can you assist on that?

AbstractPollingIoProcessor is shorter than 1151 lines while in the exception
trace we can see that line 1151 is the cause of the exception.
The pb is that either your JVM is giving the wrong line number (very
unlikely) or you are *not* using MINA 2.0.2.
From the svn repository, the only revisions that contains a 1151 line
number are :
http://svn.apache.org/viewvc/mina/branches/2.0/mina-core/src/main/java/org/apache/mina/core/polling/AbstractPollingIoProcessor.java?revision=995776view=markup
1151 ExceptionMonitor.getInstance().exceptionCaught(t);
http://svn.apache.org/viewvc/mina/branches/2.0/mina-core/src/main/java/org/apache/mina/core/polling/AbstractPollingIoProcessor.java?revision=899977view=markup
1151 if (newSessions.isEmpty() isSelectorEmpty()) {
and they are intermediate versions between RC1 and 2.0.1...
Can you check the jars you have ?
Otherwise, I'm afraid I have even less clue about what can be your issue
than you are, as I don't have a class with 1151 lines either, and I
can't debug your code :/

Thanks for the fast reply.
This is the jar I'm using.
This is a correct jar. Its signature is the same than the one I get
when I pull 2.0.2 from the project's page...
That does not help you a lot, sadly :/
The pb is that we don't have the right line number, and I can't debug
the code...
Can you connect on IRC, channel #mina so that we chekc a few other
things ? I'm a bit clueless here..
Appreciate your help on that.
Guy

Re: mina 2.0.2 - NullPointerException in AbstractPollingIoProcessor
may want to verify jar by using
minaObject.getClass().getProtectionDomain().getCodeSource().getLocation() and
or put break point and traverse here.
and if that does not help may want to decompile the class
